    thought I would explain my fuel set up,

    there is a main external pump and a secondary. The main is feed from the intank pump which you see from one of the pics. The second is a gravity feed setup. Both pumps have filters and check valves so nothing flows backwards. They both tee into a single line up ahead until it is branched off to the rails where it feeds the front of the rails first. Then on the back of the firewall there is a regulator which flows back to the tank with the pic of the -8 line dumping back into the tank.

    The first pump will power my truck to around the 700-800 mark before the second pumps needs to come in
