Frequently bought together
Description
This kit moves the gas cap into the taillight housing on a 1967–1972 Ford truck or a 1966–1977 Ford Bronco. It is a bolt-in, so there is no welding on the truck, and it gives you a hidden filler instead of one sitting in the bed floor.
Features
- No welding required — a bolt-in solution.
- CNC laser cut 18-gauge steel.
- Pre-formed and spot-welded assembly.
- High-polished 1.5" stainless steel LS-engraved fuel filler.
- Soft roller bearing stainless steel taillight hinge.
- Laser cut taillight mounting holes and stainless steel hardware.
Choose your options
- Driver side or passenger side
- Pre-welded bucket or standard bucket
- Standard screw on neck (included) or billet easy fill neck
- Red or smoked taillights, or none if you already have a set of flat back LEDs
- Add two reverse lights
- Add the gas filler delete
Fitment notes
This kit requires flat-back LED taillights. It may not work with fuel nozzles that have a vapor-sealing or pressure-seal device, as required in some states. Off-road use only.
Not included
- 1.5" ID fuel filler hose and clamps.
- The fuel tank and sending unit.
- Flat-back LED taillights, unless you add the red or smoked pair. This kit requires flat-back LEDs - a factory-depth Ford housing will not clear the bucket.
- Paint or coating.

Installation
The kit bolts in, so no welding is needed on the truck. Stainless steel hardware and laser cut taillight mounting holes are part of it.
LS Fabrication does not currently offer a hose or plumbing kit between the filler and the fuel tank — plumbing design, routing and installation are the installer's responsibility. Hold the maximum downward slope you can from the filler neck to the tank. The kit does not provide tank venting either, so your fuel tank needs its own adequate vent system or you will see slow filling, splash-back and pump shutoff.

Common questions
Does the taillight fuel filler fit a stepside bed?
No. These kits are cut and formed for the fleetside (wideside) bed on the years listed, because the filler assembly mounts behind the bedside taillight panel that a stepside bed does not have. On a stepside the usual route is a bed floor or inside box panel filler instead. Send us a photo of your bed and we will tell you which one suits it before you order.
Does the kit come with taillights?
Not by default. The kit is the filler assembly, the polished 1.5" stainless filler neck, the roller bearing taillight hinge, the mounting hardware and the push magnet. LED taillights and reverse lights are an add-on option at the top of the page, sold as a pair with a flasher included. Your original housings and lenses bolt straight back onto the laser cut mounting holes if you would rather keep them.
What size fuel hose does the filler neck take?
The neck is 1.5" in diameter, so it takes 1.5" ID fuel filler hose and a matching hose clamp. Both are ordinary parts-store items. A tank with a side fill bung is the easiest thing to plumb it into.
Will it work with every gas pump?
It may not work with fuel nozzles that carry a vapour sealing device or pressure seal, which is what most California pumps use. Everywhere those nozzles are not mandated, the filler takes a normal nozzle. If the truck fills slowly after the install, the cause is almost always the routing of the fill hose rather than the neck itself - keep the run as short and as straight as you can and avoid a high loop that traps air.
How do I know it fits my truck?
This part is listed for 1967–1972 Ford F100, F150, F250, F350 and Bronco. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
How long before it ships?
It is a stock item and leaves our warehouse in 1-3 business days. Transit after that is typically 2-5 business days in the United States. Larger orders can arrive in more than one box on different days.
