Not sure if I posted any pics of this set up elsewhere or not so went up to the shop and took a few of what I have. The fuel fill itself came from a 90s Chevy Lumina. Also had to fab a copper elbow I got from a plumber friend of mine to get the correct turn towards the under bed tank. Used fuel hose for both fill and vent lines. The fill cap is centered on the left driver side wheel well hump at about 12'' up from bed floor.
Fills quick with no burping at all. The hose for the tank vent I routed up over the wheel well hump using strap clamps and existing bolt holes. Did this about 10 years ago or more so and have been very pleased with it. Simple but effective.
Hope it helps.
