I have a question. I just recently did the upgraded wiring for my cobra duel pumps and I ran a 10gauge wire to a relay, then to the fpdm then a 10guage another wire from the fpdm to my pumps. I fallowed this guide (Link Below) and the car runs, but when i give it throttle it flutters and tries to die. (i'm extremely low on gas and that is probably why)

but the main question i have is about the priming. When i turn the key to the on poition the pumps prime and keep going. They used to stop after a few seconds now they just stay on until i turn the key off. Did i mess up the wiring or do i have a bad relay?
