Description
This filler moves the fuel fill to the inside box panel of a 1967–1987 Chevy or GMC bed instead of sitting flush in the middle of the bed floor. It is an affordable and convenient spot, and it keeps the filler out from underfoot.
Features
- Raw 18 gauge mild steel, pre-formed and tacked together in case slight modifications are needed for your application.
- Weld it in, or screw it in with the supplied hardware.
- Includes our 316 stainless filler neck with a polished face and a laser-engraved LS logo.
- Flip-up cap for keyless opening and closing, with a stainless steel retaining chain so the cap stays with the truck.
- Flange with three tapered mounting holes, and stainless steel mounting hardware.
Filler neck dimensions
- Flange diameter 2-15/16".
- Neck diameter 1-1/2".
- Neck length 2-1/4".
Choose your option
- Filler neck: standard, or billet Easy Fill
- Panel: not pre-welded, or fully pre-welded
Fitment notes
A universal fill tube is required to join the neck to your tank. We recommend a side fill tank, 1.5" diameter, which you can source from a local parts store.

Installation
The panel welds in, or screws in with the supplied hardware. It ships pre-formed and tacked together, so there is room to adjust it if your bed needs it.
You will need a universal fill tube to join the neck to the tank. A side fill tank is what we recommend, 1.5" diameter.

Inside Box Panel Fuel Filler - 67-87 GMC Chevy Truck
Common questions
Will it drop straight into my bed?
Expect to modify the base slightly. The panel is built to cover a range of years, and no two beds underneath it are the same - a 67-72 floor, a 73-87 floor, a wood floor and a floor with a spray-in liner all sit at different heights. That is why the part ships in raw steel, pre-formed and only tacked together, so you can adjust it to your own bed before it goes in for good.
Can it be welded in, or does it screw in?
Either. Weld it in for a seamless finish, or screw it in using the supplied stainless hardware and the three tapered mounting holes in the flange. Customers have also riveted and bonded them in. The choice is yours.
What are the filler neck dimensions?
Flange diameter 2-15/16", neck diameter 1-1/2", neck length 2-1/4". A universal fill tube joins the neck to the tank, and a side fill tank in 1.5" is the simplest thing to run it into.
Is it sealed against water?
The flip-up cap closes onto the neck face and the retaining chain keeps the cap with the truck, but this is a fuel filler, not a watertight hatch. Anything mounted in a bed floor will see water sitting on it, so seal the panel to the floor when you fit it and treat the cap as a fuel cap rather than a gasketed lid.
How do I know it fits my truck?
This part is listed for 1967–1987 Chevy and GMC Blazer, C10, C1500, C20, C30, Jimmy 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.
