I can only speak to what I did. I had a '72 truck which already has a return line run to the factory sending unit. I used the filter and frame mounted pump from a 1988 F-150 351W with fuel injection. The pump and filter are mounted to my frame rail on the passenger side towards the rear of the cab. I utilized the factory hard lines that run the length of the frame rail. Then I added aluminum line to run across the cross member at the front of the frame and up to the tpi fuel rail. 1988 F-150 351W. Easy to work with. Cheap. Sufficient. And available at any parts store in case you break down in the middle of nowhere. K.I.S.S. design philosophy. Keep It Simple Stupid
