The fill neck will pass between the top of the frame rail and bed floor. I made some isolation pads out of some old floor tiles and glued them together then glued/RTV'd/screwed them to the bed cross rails. The thickness was the perfect spacing to clear the tank bump and space the filler neck correctly.

The HF transmission jack came in very handy for the extra hands need to lift and hold the tank in place while stuff was being prepared. I used the 84 Tank straps, but I had to remove one of the bolts and go with J-hooks to give me enough reach.

Next I took an old squarebody stepside fill door I've had lying around for 20 years and modified it to holder the suburban filler neck. Once I got it to the shape and placement I wanted I cleaned it up and painted it, then added some bed-liner to the sides hoping for it to take a little more abuse than paint.
