Hey guys. Ive got a 89 eclb k2500. Just got a new blueprint engine 383 installed, cut the ecm out, re wired stock fuel pump and relay, and put a fuel psi reg in. Everything is working how it should but i am getting excessive psi build up in the tank. Just wondering if that could be caused by to much fuel return to the tank? And is there a way to remove the stock in tank pump from the sending unit, install a ext pump and get rid of the excessive psi build up in the tank?
