Description
This taillight fuel filler moves the gas filler on a 1967–1972 Chevrolet or GMC C10 out of sight, behind a hinged taillight. It is a clean alternative to dropping the cap into the bed floor, and it relocates the stock filler without cutting up the bedside.
Features
- CNC laser cut from 18 gauge steel.
- Pre-formed and spot welded assembly, shipped with the sides tacked in place.
- High polished 1.5" stainless steel fuel filler with LS engraving.
- Soft roller bearing stainless steel taillight hinge.
- Laser cut taillight mounting holes.
- Stainless steel hardware, plus the double push magnet shown in the photos.
Choose your options
- Driver side or passenger side.
- Standard screw on filler neck or billet easy fill neck.
- Add LED taillights or reverse lights. Each is sold as a pair and includes a flasher.
Fitment notes
Taillight fuel filler kits may not work with fuel nozzles that have a vapour sealing device or pressure seal, like the ones used in California. Refer to the photos for what is included in the kit.
If you only want a filler neck to put somewhere else, look at our universal fuel filler.
Not included
- 1.5" ID fuel filler hose and the clamps to hold it - both are ordinary parts-store items.
- The fuel tank and sending unit. A side fill tank is the easiest thing to plumb the neck into.
- Taillights and lenses. Your originals bolt back onto the laser cut mounting holes, or add the LED pair at the top of the page.
- Paint or coating. The assembly ships in bare steel, tacked together, so you can adjust it to your own bed before it goes in for good.

Installation
LS Fabrication does not currently offer a hose or plumbing kit for connecting the taillight fuel filler to the tank. All plumbing design, routing and installation is the installer's responsibility.
The filler does not vent the tank. Venting has to come from the tank itself, so an aftermarket tank needs an adequate vent system. Without one you can get slow filling, fuel splash-back or the pump shutting off.

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 Chevy and GMC Blazer, C10, C20, C30, Jimmy, K10 and others. 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.
