I also made some progress on the gas tank filler neck, the angle of the filler tube wasn't to my liking as it landed in the middle of my bumper where I want to put a hitch. So I reshaped it with plenty of pie cuts and welding very carefully to make sure no pin holes existed. This way the filler cap is placed in the bed panel under the tailgate. I then used a piece of rubber hose to link the two together to compensate for any bed movement. The rubber hose came from a filler neck on an old ford truck in the junkyard, so I know it is rated for fuel. Changing the angle of the filler neck also ensures that I won't have gas pouring out the back when driving up a hill.
