A broken or missing fuel-door spring can make a 2006 Nissan Xterra fuel door hang open, fail to pop out, or require awkward manual handling at the pump. The challenge is finding a small replacement that matches the original mounting points, especially because several aftermarket listings use overlapping Nissan part numbers. When comparing 2006 nissan xterra fuel door spring, I look at how each option fits a real buying need, where it performs well, and which trade-offs matter.
My first choice is MOTOKU Fuel Door Filler Spring. Its stated Xterra coverage includes the 2006 model, and its cross-reference to 78836-ZP40A, 78836-EA000, and 78836-ZP00A gives buyers several useful ways to verify fitment before ordering.
My second choice is YQABLE Fuel Gas Filler Door Spring 78836-ZP40A. My alternative is YQABLE YQABLE Fuel Gas Filler Door Spring 78836-ZP40A.
This comparison looks at five replacement springs, their stated compatibility, construction details, part-number coverage, customer-feedback signals, and practical limitations. The buying guidance then explains how to confirm fitment, prepare for installation, avoid common mistakes, and keep a repaired fuel door working smoothly.
5 Best 2006 Nissan Xterra Fuel Door Spring
I selected these options by combining relevance to the Xterra application, the amount of useful fitment information supplied, available customer-feedback evidence, and brand variety where a reasonable alternative existed. No hands-on testing is claimed; the rankings reflect the supplied product data and how clearly each spring supports a careful buying decision.

MOTOKU Fuel Door Filler Spring
MOTOKU earns the top position because it gives a 2006 Xterra owner a particularly clear fitment path. The listing specifically covers Nissan Xterra models from 2005 through 2015, placing the target vehicle inside the stated range rather than relying only on a generic Nissan application.
Its three listed replacement numbers—78836-ZP40A, 78836-EA000, and 78836-ZP00A—are useful when comparing the old spring, a service record, or an online parts catalog. That broader cross-reference may help buyers who find that their vehicle documentation uses a different number from the one shown in a competing listing. The package contains one fuel gas tank door cover spring clip, so it is aimed at a single repair rather than a multi-pack or complete fuel-door assembly.
MOTOKU also lists compatibility with the 2005-2012 Pathfinder and 2005-2021 Frontier. Those extra applications do not automatically replace checking the Xterra’s exact design, but they show that the part is positioned as a cross-platform replacement for a family of Nissan fuel-door mechanisms. A supplied customer rating of 4.2 from 21 ratings provides more feedback context than several alternatives in this group, although it is not a guarantee of fit on every vehicle.
Pros
- Directly states compatibility with 2005-2015 Nissan Xterra models.
- Lists three replacement part numbers for easier cross-checking.
- One-spring package suits a focused repair.
- Has a 4.2 rating from 21 customer ratings.
Cons
- Does not include the surrounding fuel-door hardware or cover.
- Fitment should still be confirmed against the original spring and vehicle details.
My Opinion
This is the strongest all-around choice when a buyer wants clear Xterra coverage and multiple OE-number references in one listing. Confirm the original clip shape before ordering, because a correct year range alone cannot account for a previously modified or damaged mounting area.
YQABLE Fuel Gas Filler Door Spring 78836-ZP40A
YQABLE is a focused aftermarket option built around part number 78836-ZP40A. That narrow identification can be helpful for a buyer whose removed spring, repair paperwork, or trusted parts catalog already points to that number. The listing also names the Nissan Frontier, Pathfinder, and Xterra, making it relevant to the 2006 Xterra without adding unrelated vehicle applications.
The most useful buying advice supplied by YQABLE is to verify the OE number and compare the product photographs with the part being replaced. That matters for a small stamped or formed spring because visual differences in bends, tabs, or contact points can affect whether the fuel door releases and returns correctly. A careful photo comparison is particularly worthwhile if the old part is broken but still available for side-by-side inspection.
Unlike the MOTOKU listing, this product does not provide a stated Xterra year range in the supplied information. It also has no guide-count detail available, so the buyer has less public feedback context to weigh. Those omissions are why it sits second, not first, but they do not make it unsuitable when 78836-ZP40A is already confirmed.
Installation should be treated as a direct replacement only after the old spring and hinge area are inspected. If the fuel-door frame is bent, the hinge is seized, or the original clip was installed in a different orientation, replacing the spring alone may not restore normal operation.
Pros
- Clearly identifies part number 78836-ZP40A.
- Names Xterra, Pathfinder, and Frontier compatibility.
- Encourages OE-number and photo comparison before purchase.
- Good alternative when exact part-number matching is already established.
Cons
- No stated vehicle year range in the supplied listing details.
- No guide-count information is provided.
- Does not include additional fuel-door repair hardware.
My Opinion
YQABLE is best for a careful parts matcher rather than someone shopping by year alone. If the original spring shows 78836-ZP40A in a catalog or the product image closely matches the removed piece, it is a practical second choice; otherwise, MOTOKU offers a clearer starting point.
XNManaWork Metal Black Fuel Filler Door Spring
XNManaWork takes a different approach by emphasizing metal construction and a direct replacement design. The listing describes the spring as being made from high-strength metal intended to tolerate wear and repeated use. That can appeal to an owner who is replacing a spring that has become weak, distorted, or broken after years of opening and closing the fuel door.
The stated fitment covers Frontier models from 2005-2018, Pathfinder models from 2005-2012, and Xterra models from 2005-2015. That includes the 2006 Xterra and makes the application range easy to understand. It also identifies OEM number 78836-ZP40A, which gives the buyer a useful reference point when comparing this option with other aftermarket clips.
The product is described as an easy direct replacement that requires no special modification according to the supplied details. Even so, “direct replacement” should not be interpreted as permission to force the spring into place. A small metal clip can be installed incorrectly if the retaining tabs or spring tension points are not aligned with the original position. The listed dimensions are 1.97 by 1.97 by 1.97 inches and the item weight is 0.353 ounces, but those figures do not describe the mounting geometry by themselves.
Its 3.9 rating is lower than the two 4.2-rated options in this group, and no guide-count detail is supplied. That uncertainty, combined with the need to confirm sizing, keeps it below the first two choices despite its attractive material description.
Pros
- States metal construction for a durable replacement approach.
- Fits the listed 2005-2015 Xterra range.
- Identifies OEM number 78836-ZP40A.
- Designed as a direct replacement without modification.
Cons
- Lower supplied rating than the first two choices.
- No customer feedback-count detail is available.
- Listed overall dimensions do not replace a mounting-point check.
My Opinion
This option makes sense when material strength is a priority and the original spring clearly matches the 78836-ZP40A style. Before ordering, compare the actual bends and tabs rather than choosing it solely because “metal” sounds more durable.
OKPARZ Fuel Door Spring Clip
OKPARZ provides one of the broadest explicit Frontier applications in the group, listing Frontier years from 2005 through 2021, along with Pathfinder from 2005-2012 and Xterra from 2005-2015. For the target vehicle, the important portion is the stated 2005-2015 Xterra range, which includes the 2006 model.
The part-number coverage is also useful: 78836-ZP40A, 78836-EA000, and 78836-ZP00A are all listed as interchangeable references. That makes this spring easier to compare with an original component or an earlier parts lookup. The package includes one gas-door spring and a stated one-year unlimited-mileage warranty, which adds a defined support term that is not listed for most of the other aftermarket choices.
OKPARZ describes the part as a new aftermarket replacement that does not require modification. The practical benefit is a repair intended to restore the fuel-door release without changing the vehicle’s surrounding structure. Still, the warranty does not eliminate the need to check fitment, and the product will not correct a cracked door, damaged hinge, or distorted body panel.
The supplied rating is 3.8 from 20 ratings, below the 4.2 scores attached to MOTOKU and YQABLE. That feedback signal places it fourth, but the clear cross-reference list and one-year warranty may matter to buyers who value defined replacement support over a slightly higher aggregate rating.
Pros
- Explicitly covers 2005-2015 Nissan Xterra models.
- Lists three commonly associated replacement numbers.
- Includes a stated one-year unlimited-mileage warranty.
- One spring is included for a single repair.
Cons
- Supplied rating is 3.8 from 20 ratings.
- Aftermarket construction is not described in detail.
- Cannot repair damaged fuel-door panels or hinges.
My Opinion
OKPARZ is a reasonable backup when its three part numbers match the old clip and the warranty is important to you. I would place it ahead of a less clearly identified option, but behind the higher-ranked choices because its customer-feedback signal is weaker.
Nissan Nissan Parts Fuel Door Spring 78836-3S500
This Nissan-branded spring stands apart from the other four selections because the supplied information identifies it as a genuine OEM part rather than an aftermarket replacement. It is described as vehicle-specific, Nissan quality assured, and covered by a manufacturer warranty. Those qualities can be attractive to an owner who prefers a manufacturer-branded component over a cross-compatible substitute.
The stated model is Genuine Nissan Parts Fuel Door Spring 78836-3S500, and the item number is 78836-3S500. Its supplied rating of 4.5 from 10 ratings is the highest numerical rating in this group, although the smaller number of ratings means it provides a narrower customer-feedback sample than MOTOKU or OKPARZ.
The main concern is application verification. The listing does not state that 78836-3S500 fits a 2006 Xterra, nor does it provide the overlapping Xterra, Pathfinder, or Frontier year ranges shown by the aftermarket choices. A genuine Nissan label does not automatically mean that every Nissan spring with a similar function fits every Nissan vehicle, so this option should be purchased only after a Nissan parts catalog, dealer, VIN lookup, or original-part comparison confirms the number.
It also appears to be a spring alone, not a complete fuel-door assembly. If the vehicle’s opening problem comes from a damaged body-side bracket or worn hinge, an OEM spring by itself may not solve the entire issue.
Pros
- Identified as a genuine OEM Nissan component.
- Vehicle-specific positioning may appeal to factory-part buyers.
- Includes manufacturer warranty information.
- Highest supplied rating at 4.5 from 10 ratings.
Cons
- Fitment for a 2006 Xterra is not stated in the supplied data.
- Uses part number 78836-3S500 rather than the numbers listed by most alternatives.
- May require more careful catalog or VIN verification before purchase.
My Opinion
This is the best candidate only for a buyer who confirms that 78836-3S500 is the correct factory number for the specific Xterra. Without that confirmation, the explicit Xterra fitment and cross-reference information of the higher-ranked aftermarket springs make them safer shopping choices.
How I Selected These Springs for the 2006 Xterra
The selection starts with application relevance. A replacement spring must be associated with the Xterra rather than merely described as a universal fuel-door component. Four listings explicitly include Xterra model years that cover 2006, while the Nissan-branded option requires separate confirmation because its supplied details do not state Xterra compatibility.
I also gave weight to part-number clarity. Numbers such as 78836-ZP40A, 78836-EA000, and 78836-ZP00A allow a buyer to compare listings more intelligently than a generic phrase like “fuel door clip.” They are not a substitute for a VIN-based catalog check, but they create a practical bridge between the old component, vehicle records, and replacement listings.
Customer feedback was considered as supporting evidence rather than proof of fit. MOTOKU has a 4.2 rating from 21 ratings, OKPARZ has a 3.8 rating from 20 ratings, XNManaWork is listed at 3.9, YQABLE at 4.2, and the genuine Nissan part at 4.5 from 10 ratings. Because customer-feedback volume are missing for some products and ratings do not reveal every vehicle configuration, the ranking also considers fitment detail, warranty information, and the clarity of the product description.
For this small repair, a clearly matched part number is usually more useful than a broad claim of universal compatibility.
Brand variety also mattered. The list includes several aftermarket choices and one genuine Nissan option so buyers can compare direct replacement convenience with manufacturer-branded sourcing. This is a parts-information comparison, not a hands-on durability test.
How to Choose a 2006 Xterra Fuel Door Spring
The right spring is the one that matches the vehicle’s mounting design and the original part reference, not necessarily the one with the longest compatibility list. Start with the old clip if it is still present, then compare its shape, tabs, bends, and contact points with the listing photographs or catalog illustration.
- Confirm the year range: A listing that explicitly includes 2005-2015 Xterra models is easier to assess for a 2006 vehicle than one that names Nissan generally.
- Match the part number: Check 78836-ZP40A, 78836-EA000, 78836-ZP00A, or another verified number against the original component and a reliable catalog.
- Compare physical shape: Look for matching bends, retaining tabs, spring arms, and contact surfaces rather than relying on dimensions alone.
- Decide between aftermarket and OEM: Aftermarket choices offer more explicit cross-reference information here, while the Nissan part may suit buyers who confirm its exact factory application.
- Inspect the surrounding hardware: A spring cannot correct a bent fuel-door frame, broken hinge, missing retainer, or corrosion that prevents free movement.
Part number versus vehicle year
Year-based fitment is a useful first filter, but the part number is often the stronger confirmation. Nissan vehicles can share components across several platforms, and an aftermarket seller may list multiple replacement numbers for one spring design. Conversely, a manufacturer part number may be accurate but still belong to a different application.
For a 2006 Xterra, the safest process is to use both sources: verify that the listing names the Xterra range and verify that the replacement number matches a trusted parts reference. If those two checks disagree, pause the purchase instead of assuming the listing is correct.
When material claims matter
XNManaWork specifically emphasizes high-strength metal construction, which may interest buyers concerned about repeated flexing or a spring that failed from fatigue. However, material language cannot tell you whether the part has the correct shape or tension. A perfectly strong spring that does not seat correctly is still the wrong repair.
How to Confirm Compatibility Before Ordering
Begin with the vehicle identification information and the part currently installed. If the old spring is missing, photograph the empty mounting area from several angles and compare it with the product images. The goal is to identify where the spring anchors, which direction it pushes, and whether the replacement has the same basic profile.
Use the original part as a reference
Remove loose fragments carefully and keep them until the replacement arrives. A broken spring may still reveal the original bend, hook, or flat retaining section. Do not discard those pieces before comparing them, because a small difference in orientation can explain why a generic-looking replacement does not work.
Check the complete repair area
Open and close the fuel door gently before removing anything. Note whether the door sticks, sits low, fails to spring outward, or refuses to stay closed. These symptoms can point to more than a weak spring, including hinge friction, body-panel damage, or a misplaced fuel-door release component.
Also inspect for previous repairs. A bent bracket or altered retaining edge may cause an otherwise correct clip to fit poorly. If the surrounding panel has been repaired or replaced, a catalog match should be followed by a visual comparison with the actual vehicle.
Basic Installation Planning
A fuel-door spring is small, but installation can be frustrating if the work area is cramped or the replacement is forced. Gather basic hand tools appropriate for the vehicle’s fasteners, a flashlight, protective gloves, and a small container for removed hardware. The exact tool list can vary depending on access and whether the spring is attached to the door or the body-side frame.
Prepare before removing the old clip
Take a clear photo of the old spring while it is still installed. Marking its orientation in a quick sketch can be more useful than memory, particularly when the clip has several similar-looking arms. Clean dirt around the mounting area so the retaining points are visible, but avoid pushing debris into the hinge or filler area.
Compare the new spring with the old one before installation. The replacement should have a comparable overall profile and contact arrangement. If it appears reversed, substantially different, or unable to reach the same anchor points, stop and recheck the part number instead of bending it to fit.
Seat the spring without forcing it
Install the spring in the same orientation as the original and engage each retaining point gradually. Excessive prying can deform a thin clip, damage the fuel-door frame, or weaken the replacement before the door is used. If the component requires unusual force, the likely causes include incorrect orientation, an obstructed mounting point, or an incompatible spring.
After installation, operate the door slowly several times. It should move without scraping, remain aligned with the surrounding panel, and close without excessive pressure. Do not treat a door that barely works as a successful repair; a misaligned spring can fail again or place stress on the door and bracket.
Testing the Repaired Fuel Door
Functional testing should be simple and controlled. With the vehicle parked safely, open the fuel door from its normal release mechanism and observe whether it moves outward consistently. Then close it gently and check whether it sits flush rather than high, low, or angled.
- Confirm the door releases without being pulled aggressively.
- Check that the spring does not rub against the body panel.
- Make sure the door closes fully and stays closed.
- Look for movement of the surrounding bracket or trim.
- Repeat the open-and-close cycle several times without forcing it.
If the spring works only when the door is pushed sideways, inspect the hinge and panel alignment. If it pops open too forcefully, verify that the spring is seated correctly rather than assuming stronger tension is better. Normal operation should be smooth and repeatable.
Maintenance and Long-Term Ownership Tips
The spring itself needs little routine attention, but the surrounding fuel-door mechanism benefits from occasional inspection. Road grit, salt, and moisture can collect around the hinge and mounting area, increasing resistance and making the spring work harder. Wipe away visible dirt with a suitable cloth and avoid packing the area with thick products that attract more debris.
Do not bend the door outward to make refueling easier. Repeated leverage on the door can distort the hinge or body-side bracket, creating a problem that a replacement spring cannot solve. If the door becomes stiff, investigate the cause early rather than repeatedly forcing it.
A light, vehicle-appropriate lubricant may be suitable for a hinge if the manufacturer or repair instructions permit it, but avoid spraying blindly around the fuel-filler opening. Keep any product away from areas where it could contaminate the filler neck or attract grit. The spring’s mounting points should remain clean and properly seated.
Signs that the spring is not the only problem
A new spring may not be enough if the door is visibly bent, the hinge is loose, the retaining frame is cracked, or the release mechanism does not move. A fuel door that stays open because of a damaged panel needs a broader repair assessment. Likewise, repeated spring failures may indicate binding or misalignment rather than poor replacement quality.
If the door still needs force after a correctly matched spring is installed, inspect the hinge and frame before buying another spring.
Common Mistakes to Avoid
Most problems with this repair come from assuming that similar-looking clips are interchangeable or from forcing a part that is not aligned. A few careful checks can prevent a small, inexpensive repair from turning into damage to the fuel-door panel.
- Buying by appearance alone: Two clips may look similar in a small listing photo while using different tabs or spring angles.
- Ignoring the part number: Verify the original number whenever possible instead of relying only on a broad vehicle description.
- Skipping the photo comparison: Product photos can reveal a different bend, hook, or retaining shape before the order is placed.
- Forcing the installation: Excess pressure can deform the spring or damage the mounting frame.
- Replacing the spring without checking the hinge: Binding, panel damage, or a loose bracket may be the actual cause.
- Discarding the old part too early: The broken component can provide valuable orientation and shape information.
FAQ About the Xterra Fuel Door Spring
Does a 2006 Xterra use the same spring as later Xterra models?
The aftermarket listings from MOTOKU, YQABLE, XNManaWork, and OKPARZ state compatibility with Xterra models that include 2006 and extend through later model years. Even so, confirm the original part number and physical shape before ordering, especially if the vehicle has had body repairs.
What part numbers are associated with the Xterra fuel-door spring?
The supplied aftermarket listings reference 78836-ZP40A, 78836-EA000, and 78836-ZP00A. The genuine Nissan listing uses 78836-3S500. These numbers should be treated as identification references, not automatic proof that every number fits every 2006 Xterra.
Is the fuel-door spring sold as a complete fuel-door assembly?
No. The listed products are spring clips or replacement springs. They do not include the complete fuel door, surrounding body frame, hinge assembly, or every related retainer. If those parts are damaged, the spring alone may not restore normal operation.
Which replacement is easiest to verify for a 2006 Xterra?
MOTOKU is the easiest starting point from the supplied data because it explicitly lists 2005-2015 Xterra compatibility and provides three replacement numbers. OKPARZ also gives the same Xterra range and cross-reference numbers, while YQABLE is best verified through 78836-ZP40A and its product photos.
Should I choose the genuine Nissan spring automatically?
Not automatically. The genuine Nissan 78836-3S500 may be appealing, but the supplied listing does not confirm 2006 Xterra fitment. Verify the number through a Nissan catalog, dealer, VIN lookup, or the original spring before choosing it over an aftermarket part with explicit Xterra coverage.
Can I install the replacement without modifying the vehicle?
The XNManaWork and OKPARZ listings describe direct replacement installation without modification. The actual job still depends on the condition of the vehicle’s mounting area. Do not force or reshape the spring if the tabs do not align naturally.
Final Thoughts
For a 2006 Nissan Xterra fuel door spring, MOTOKU Fuel Door Filler Spring is the best overall choice because it combines explicit Xterra coverage with three useful replacement numbers and the strongest supplied fitment context. YQABLE YQABLE Fuel Gas Filler Door Spring 78836-ZP40A is the best alternative when 78836-ZP40A matches your original part and the product photos look correct.
