A broken fuel-door hinge can leave the gas flap loose, misaligned, or unable to stay closed. Choosing the right f150 fuel door spring means matching the truck’s model year and deciding whether you need only a replacement spring or a stronger hinge-and-pin repair kit.
My first choice is COLOFULWAY Fuel Door Hinge Pin and Gas Door Spring. Its redesigned aluminum hinge, coated spring, washer, and R-type cotter pin create a more complete repair than replacing a spring alone, while the listed fitment covers several related Ford and Lincoln applications.
My second choice is Autoacc Fuel Door Spring. It focuses on replacing the failed spring without requiring the full housing, making it appealing when you want a simpler, lower-part repair for a later-model truck.
This comparison covers five replacement options, including spring-only parts and complete hinge repair kits. You’ll learn which model years each part fits, what comes in the package, where installation may be more involved, and how to avoid the most common compatibility mistakes.

COLOFULWAY Fuel Door Hinge Pin and Gas Door Spring
The COLOFULWAY kit earns the top position because it addresses more than the spring itself. It is designed for 2009–2014 F-150 fuel doors and includes a redesigned aluminum hinge, a coated fuel-door spring, washer, and R-type cotter pin. That combination is useful when the original plastic hinge has worn, cracked, or no longer holds the door correctly.
Instead of replacing the entire housing or buying another complete door assembly that may contain the same weak plastic design, this kit gives the buyer a metal hinge repair. The maker describes the connection as sturdy, reusable, and free from the need for lubricant or adhesive. That should appeal to someone looking for a lasting mechanical fix rather than a temporary adjustment.
The listed pin diameter is 0.43 inches, and the application list also includes 2010–2014 Lincoln Mark LT, 2010–2012 Ford Fusion, 2010–2012 MKZ, and 2010–2011 Milan fuel doors. However, the housing or pocket is not included, so the existing surrounding structure must still be suitable for the repair. Confirming the truck’s exact year and hinge layout before ordering is especially important.
Pros
- Complete hinge, spring, washer, and cotter-pin repair kit
- Aluminum hinge replaces the vulnerable plastic hinge design
- Broad listed fitment for 2009–2014 F-150 and related vehicles
- Reusable repair approach without adhesive or lubricant
Cons
- Housing or fuel-door pocket is not included
- Not intended for F-150 model years outside the listed range
- May require careful removal of the original hinge components
My Opinion
This is the strongest all-around choice when a 2009–2014 F-150 has both a failed spring and a damaged plastic hinge. Buyers who only need a spring may prefer a simpler part, but this kit offers better coverage for a loose or poorly supported fuel door.
Autoacc Fuel Door Spring
The Autoacc replacement is a focused spring-only solution for 2015–2020 F-150 models. It is also listed for 2011–2019 Explorer applications and references part number FL34-9927936-A, which gives buyers an additional way to compare the part against their existing component or vehicle records.
Its main advantage is simplicity. If the fuel-door housing and hinge remain intact but the spring has lost its tension or broken, replacing only that spring can avoid purchasing a complete housing assembly. That makes this option appropriate for a buyer who has diagnosed the spring as the only failed piece and does not need an aluminum hinge conversion.
Installation deserves attention because the supplied information specifically notes that removing the spring can be harder than on 2009–2014 models. The spring should be inserted into the top hinge portion before installation, so rushing that step or placing it in the wrong orientation could make the repair frustrating. A free exchange and return service is also stated, but compatibility should still be checked before starting the job.
Pros
- Direct spring replacement for 2015–2020 F-150
- Useful when the original housing and hinge are still sound
- Also listed for 2011–2019 Explorer
- Installation guidance identifies the correct top-hinge placement
Cons
- Does not replace a worn or broken hinge
- Spring removal may be more difficult on these applications
- Only one spring is supplied
My Opinion
This is the better-value style of repair for a later F-150 with an otherwise healthy fuel-door assembly. It ranks below the first product because it cannot solve a damaged hinge, but it avoids unnecessary extra hardware when the failure is limited to the spring.
Txouoxt Fuel Door Hinge Pin and Gas Door Spring
The Txouoxt kit is aimed at 2015–2020 F-150 fuel doors with a loose gas flap caused by failure of the original plastic hinge. It includes an aluminum replacement hinge, a fuel-door spring, washer, and R-type cotter pin. That makes it a fuller repair than a spring-only replacement and gives the buyer a way to address the support point that often allows the door to sag or stop closing properly.
The aluminum hinge is intended to provide a more durable alternative to the original plastic component. For a truck that has already experienced repeated hinge wear, this approach may be more sensible than installing another spring while leaving a weakened hinge in place. It is also positioned as a less expensive option than replacing the complete door assembly.
The stated fitment covers 2015–2021 F-150 fuel doors, while the source title emphasizes 2015–2020. Because those ranges do not match perfectly, buyers with a 2021 truck should verify the listing and compare the existing hinge before ordering. The housing or pocket is not included, so this is a component-level repair rather than a complete fuel-door assembly.
Pros
- Combines a replacement spring with an aluminum hinge
- Includes washer and R-type cotter pin for retention
- Addresses loose-door problems caused by a failed plastic hinge
- Potentially avoids replacing the entire fuel-door assembly
Cons
- Housing or pocket is not included
- Fitment wording differs between 2015–2020 and 2015–2021
- More involved than replacing a spring alone
My Opinion
This is a sensible middle-ground option for a 2015–2020 F-150 when both the spring and hinge deserve attention. Its stated 2021 coverage should be treated as a verification point rather than an automatic guarantee, which keeps it behind the more clearly positioned choices.
ROOTMUTIFY Fuel Door Hinge Pin and Gas Door Spring
The ROOTMUTIFY kit has the broadest stated F-150 year range in this group, covering 2015–2024 models. It pairs an all-aluminum custom hinge with a carbon-steel spring, washer, and R-type cotter pin. The material choices are intended to improve resistance to wear and corrosion compared with the original plastic hinge and spring arrangement.
This kit may suit a newer-truck owner who wants to repair the hinge mechanism without replacing the entire fuel-door assembly. The included parts are focused on the hinge area, so the solution remains relatively targeted. It does not fit Flareside, stepside, or Heritage models, a limitation that should be checked before considering the year range.
Installation instructions are more detailed than those supplied for several competing kits. They explain that the painted door cover should be removed and that the inside tab must be pulled out rather than pushed in. Small flat screwdrivers are recommended for gently depressing the clip from the front, with the guidance emphasizing that the part should be pivoted out rather than forced from below. Those instructions may help, but the job still calls for patience around painted trim.
Pros
- Broad listed coverage for 2015–2024 F-150 models
- Aluminum hinge and carbon-steel spring are intended for durability
- Includes washer and R-type cotter pin
- Provides specific trim-removal guidance
Cons
- Does not fit Flareside, stepside, or Heritage models
- Housing or pocket is not included
- Removing the painted door cover may require extra care
My Opinion
ROOTMUTIFY is attractive for a later F-150 owner who values wide stated year coverage and detailed installation direction. Its lower position reflects the smaller customer-feedback sample and the need to confirm body style, not a lack of useful repair hardware.
KPALAG KPALAG Fuel Door Hinge Pin Gas Door Spring
The KPALAG repair kit is designed for 2009–2014 F-150 models and several related vehicles, including the 2010–2014 Lincoln Mark LT, 2010–2012 Ford Fusion, 2010–2013 MKZ, and 2010–2011 Mercury Milan. It includes one aluminum hinge pin and one fuel-door pocket spring, giving older-truck owners a compact alternative to replacing the complete filler-pocket assembly.
Several replacement part numbers are listed, including 9L3Z9927936B, 9E5Z-5427936-A, 924802, and 924-802. These references can help shoppers compare the kit with an existing repair record or parts lookup, but they should support—not replace—checking the vehicle’s year and body style.
The installation sequence is clearly described: place the fuel-door lid clip into the top hinge section, insert the hinge pin into the fuel-filler pocket, and connect the other end of the spring to the housing buckle. The kit does not fit Flareside, stepside, or Heritage models, and the housing itself is not included. That means it works best when the surrounding pocket is still usable.
Pros
- Useful aluminum pin-and-spring repair for 2009–2014 F-150
- Includes multiple reference part numbers
- Fits several related Ford, Lincoln, and Mercury applications
- Provides a straightforward installation sequence
Cons
- Not compatible with Flareside, stepside, or Heritage models
- Housing or pocket is not included
- Smaller customer-feedback sample than the top-ranked option
My Opinion
KPALAG is a useful alternative for an older F-150 when the buyer wants both the pin and spring in one small kit. It ranks fifth because the first option offers a similarly targeted repair with more supplied product detail and stronger customer-feedback evidence.
How I Selected These F150 Fuel Door Spring Options
The selection process began with fitment because a spring or hinge pin that does not match the fuel-door design will not solve the problem. I then compared whether each product replaces only the spring or also repairs the hinge, since those are different needs even when the symptom is the same loose fuel flap.
Included hardware also mattered. Aluminum hinge components, washers, cotter pins, and stated spring materials can make a kit more complete, while a spring-only product may be preferable when the existing hinge is undamaged. I gave additional consideration to installation notes, body-style exclusions, related vehicle coverage, and customer-feedback volume where supplied.
Selection takeaway: A spring-only part is not automatically inferior; it is simply intended for a narrower failure. A hinge-and-pin kit is more useful when the original plastic support has also failed.
Brand variety was retained where the alternatives served different model years or repair situations. The final order favors clear fitment, practical repair scope, and useful evidence rather than assuming that the broadest year range is always the best choice.
How to Choose an F150 Fuel Door Spring
Start by identifying the exact truck year and body style, then inspect the fuel-door mechanism with the flap open. Determine whether the spring has lost tension, whether the plastic hinge is cracked, or whether the surrounding housing is damaged. That diagnosis will tell you whether a spring-only replacement is enough.
- Match the model year: 2009–2014 and 2015–2020 F-150 applications use different repair approaches in this selection.
- Check the body style: Flareside, stepside, and Heritage models are excluded by several listed kits.
- Choose the repair scope: Select a spring-only part for an intact hinge or a pin-and-hinge kit for a broken plastic support.
- Confirm included parts: Housing and pocket assemblies are not included with these kits.
- Compare installation demands: Later-model spring removal and painted-door-cover removal may require more patience.
Spring-only replacement or complete hinge kit?
A spring-only replacement makes sense when the door still sits squarely and the hinge is not cracked or excessively loose. It minimizes the number of parts being changed and may be easier to justify when the failure is clearly limited to spring tension.
A hinge kit is more appropriate when the door will not stay aligned, the original hinge has broken, or the plastic support is visibly damaged. Installing only a new spring in that situation may leave the underlying weakness untouched.
Why body style matters
Some product listings specifically exclude Flareside, stepside, and Heritage models. Those terms describe important body or bed configurations, not minor trim differences, so do not assume that a matching model year guarantees compatibility.
If the truck has an unusual bed configuration, compare the hinge shape and pocket arrangement before buying. A clear photo of the existing mechanism can also help when contacting the seller.
Compatibility Checks Before Ordering
Use the vehicle year as the first filter, but do not stop there. The supplied products cover different ranges, and some listings use slightly different ending years in the title and fitment details.
For 2009–2014 F-150 owners
The COLOFULWAY and KPALAG kits are aimed at this older application group. Both are component-level solutions, so the existing fuel-door pocket must be reusable. The KPALAG listing also excludes Flareside, stepside, and Heritage versions, while those body-style restrictions should be treated seriously for any similar kit.
For 2015 and newer F-150 owners
Autoacc is the spring-only choice for 2015–2020, while Txouoxt and ROOTMUTIFY provide hinge-and-spring options. Txouoxt has differing 2020 and 2021 wording, and ROOTMUTIFY lists 2015–2024, so later-model buyers should verify the exact application before purchase.
Check the surrounding housing
None of the ranked options supplies the complete housing or pocket. If that structure is cracked, badly distorted, or missing its mounting points, a replacement spring or hinge pin alone may not restore proper alignment.
Installation and Setup Guidance
Read the product instructions before removing anything, and work slowly around painted fuel-door trim. The most important setup detail shared by the supplied information is correct spring placement in the top hinge area before the pin or cover is installed.
- Open the fuel door and inspect the spring, hinge, pin, and surrounding pocket.
- Compare the replacement parts with the original pieces before disassembly.
- Remove the old hardware carefully, avoiding unnecessary pressure on painted clips.
- Place the spring into the correct top hinge portion when the instructions call for that sequence.
- Install the hinge pin, washer, and R-type cotter pin as supplied.
- Move the door slowly several times and confirm that it closes evenly without binding.
For kits requiring removal of the painted door cover, use small flat screwdrivers and protect the finish from slipping tools. The ROOTMUTIFY instructions say the inside tab should be pulled out rather than pushed in, so following that direction can help prevent damage to the retaining clip.
Installation caution: Do not force the fuel door closed to test a misaligned repair. Stop and reposition the spring or hinge if the door binds, sits crooked, or requires unusual pressure.
How to Make the Repair Last Longer
A properly fitted replacement still benefits from gentle use. Open the fuel door by its normal edge rather than pulling sideways, and avoid leaning on the flap while refueling.
- Keep dirt and road debris from accumulating around the hinge and pocket.
- Inspect the spring position if the door begins sitting unevenly again.
- Do not add adhesive to a kit designed to use a pin, washer, and cotter pin.
- Replace damaged retaining hardware rather than reusing a visibly bent piece.
- Address corrosion or a distorted housing before installing another spring.
The aluminum hinge designs are intended to be reusable, but that does not mean the surrounding pocket is indestructible. Repeated slamming, side loading, or forcing the door against an obstruction can damage the parts that the kit does not replace.
Common Mistakes to Avoid
Most failed fuel-door repairs come from ordering by appearance alone or replacing the spring without checking the hinge. A few minutes of inspection can prevent buying a part that cannot address the actual fault.
- Ignoring the model year: A spring for a 2015–2020 truck is not a substitute for a 2009–2014 application.
- Overlooking body-style exclusions: Flareside, stepside, and Heritage models may not accept the listed repair.
- Assuming the housing is included: These kits provide hinge and spring components, not the complete pocket.
- Installing the spring backward: Incorrect placement can prevent proper tension and door alignment.
- Forcing painted trim: Excessive prying can damage clips or the finish around the fuel door.
- Replacing only the spring when the hinge is broken: The original failure may return because the support remains weak.
Signs You Need More Than a Spring
A spring is probably not the only problem if the fuel door hangs low, shifts side to side, or refuses to line up with the surrounding body panel. Visible cracking around the hinge or a missing pin also points toward a hinge-and-pin repair rather than a spring-only part.
If the pocket itself is broken, a component kit may not be enough. The ranked products are designed to repair the hinge mechanism, so inspect the mounting area before ordering and confirm that it can securely hold the replacement hardware.
F150 Fuel Door Spring FAQ
What is the best f150 fuel door spring for a 2009–2014 truck?
The COLOFULWAY hinge pin and gas door spring kit is the strongest overall choice in this comparison for 2009–2014 F-150 models. It includes an aluminum hinge, spring, washer, and R-type cotter pin, making it suitable when the plastic hinge and spring both need attention.
Should I buy a spring-only replacement?
Choose a spring-only replacement when the hinge and surrounding housing are intact and the door problem is limited to lost spring tension. If the hinge is cracked, loose, or missing its pin, a complete hinge-and-spring kit is more appropriate.
Does the Autoacc spring fit every F-150?
No. The supplied fitment lists Autoacc for 2015–2020 F-150 models. It should not be assumed to fit earlier or later trucks without confirming the application.
Do these kits include the fuel-door housing?
No. The listed hinge repair kits specify that the housing or pocket is not included. The existing pocket must remain usable for the replacement hinge and spring to work correctly.
Are Flareside or Heritage F-150 models supported?
Several listings specifically exclude Flareside, stepside, and Heritage models. Confirm the truck’s body style before ordering, even when the model year appears to match.
What should I check after installing the spring?
Move the fuel door slowly and confirm that it opens, closes, and sits flush without rubbing. Check that the spring remains seated, the hinge pin is retained, and the door does not require excessive force.
Final Thoughts
For an older truck with a failing plastic hinge, the COLOFULWAY Fuel Door Hinge Pin and Gas Door Spring for 2009–2014 F-150 is the best overall pick. For a 2015–2020 F-150 whose hinge is still sound, the Autoacc Fuel Door Spring is the simpler choice. Match the year and body style carefully before ordering any f150 fuel door spring repair.
