Metal Bed Fuel Door Adapter | Ford, Chevy and Dodge Trucks
Flush mount. No visible hardware. Metal bed. Wood bed builders have had the clean hidden fuel door for years. Every metal bed owner who saw one asked the same question - what about us. This is the answer. The adapter bridges our proven wood bed fuel door system to a steel bed; so the door sits flush and the bed side keeps its line with nothing bolted across it. A TPU 3D printed gasket comes in the box. That is what takes the rattle out and keeps the seal tight over a washboard road; the same TPU we have run across countless FFG builds. Choose your material. 3D printed unfinished if you are painting it to match; or billet aluminum in polished; black Cerakote; brushed or bronze. The fuel door itself is sold separately. This adapter is the mount that makes it work on steel.
Install Level: Intermediate - bed side cutout and flush mount fitment
The Wood Bed Fuel Door is sold separately; this is the adapter that mounts it to a metal bed.
TPU 3D printed gasket included for a tight seal and zero rattle.
Installation hardware included.
Material options: 3D printed unfinished; billet aluminum polished; billet aluminum black Cerakote; billet aluminum brushed; billet aluminum bronze.
The 3D printed unfinished version arrives ready for your own paint.
