[QUOTE="COOL COBRA, post: 16997029, member: 144330"] My career was in the oilfield. We got free fuel from the rig & 90% of us drove diesel pickups. I plumbed 3 trucks of mine like this & helped countless others do the same. Two were L shaped tanks with a toolbox sitting on it & the last one was a square tank. Same concept. They all had a 3/8 drain on the side to screw the valve into & a 3/8 vent on top. The vent on top has to be finger tight or less, just screwed in about 1 turn or the tank will vacuum lock once you open the drain valve. For some reason the drain was always on the passenger side. Screw in a “street L” there. It’s a Male x Female 90 degree fitting. Screw the ball valve into that & lay the fuel hose behind the tank, there’s room. Drill a hole in the inner fender well just above the bed floor to run the hose through. Then drill a 3/8 hole in the upper most part of the filler neck & screw in a 3/8 hose barb. When you unscrew the truck fuel cap you can see the fuel flowing in approximately 1 1/2” down inside the filler neck. I shit you not, I drove 500k + miles with this simple setup. [/QUOTE]
