SHAVING GAS DOOR

were do i reroute my gas line to after i shave my gas door and do i have to get a fuel cell.just static dropping my truck not bagging it but really like the clean look u get after shaving everything.

when i did mine i cut the metal filler tube and turned it around so i pointed to the inside of the bed then took off that cover that covers the back side of the filler and made a little bracket to hold the filler tube so it pointed to the inside of the bed.

I did like slow50 but cut and rewelded the filler tube so it would bolt up to that cover on the inside after I had drilled a hole with a hole saw and look stock. no pics sorry
