So I was wandering what the best setup for a 75 or so gal diesel tank for the bed. Make it so you refill your fuel tank, or hook it up to your system. Thanks a lot, George

 

When I was hotshoting I had 50 gallons in the bed. It was connected to filler neck of the truck tank. I had a generic little fuel pump and a fuel selector valve part#fsv1 from a ford with two tanks. I used a driving light relay with two 12v outs to power it all. One switch on the dash opened the valve and started the pump at the same time. I did use a ball valve at the tank so I could shut it all down for filter changes. It wasn't fuel pump fast, but it was faster than gravity feed. Hope this helps.
