For the fuel system, I chose to keep the tank in the cab. I'm not a fan of external pumps, so I made a few modifications to use an in-tank setup.
First, I turned out a plate on the lathe to fit in the stock sending unit location:
Then I used a JIC 6 bulkhead fitting with the stock feed line which will be used for a return.
I built my own pump hanger. I started by turning an electrical bulkhead out of nylon. Here it is with a push nut, o-ring, and a quarter to show scale.
Here it is, assembled:
Here is a reinforcement ring, gasket, and block-off plate that I ordered from Tanks, Inc.
