Hidden Tail Light Fuel Filler Kit – 88-98 GMC Chevy OBS Truck

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.

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.

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.

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.

This part is listed for 1988–1998 Chevy and GMC Blazer, C1500, C2500, C3500, Jimmy, K1500 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.

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.
