Is the aftermarket pump rated at enough pressure for your fuel injected engine? I had a aluminum cell built for my truck and shortened the stock sending unit/ pump to fit in it. One of the plugs is for the sending unit and the other will be the power for the pump (black I think). I think one wire is hot, one ground and one is for the prime like when you turn the key on and the pump runs for a few seconds then cuts off. Not sure exactly how you should wire it into the other pump though. I woul try ls1tech.com or performancetruck.net on the wiring.
