I wanted to keep the filler out of the box and I couldn’t find a place on the outside of the Fleetside box side that would work so I decided on utilizing the original filler location.
I bought fuel compatible hoses, one with 1” ID and the other 3/4” ID. That matches the fill and filler vent necks on the tank. I also bought a 76 Jeep filler and cap assembly, which fit nicely in the OEM style filler, rubber gasket. I ran the hoses thru the floor, along the outside of the frame rail and clamped them to bed cross sills. I neglected to get any pictures of the hose runs.
