LS swap on an 87 TBI
I’m most of the way finished with swapping an ls3/6l80 into my 87 GMC R1500. My question is what wire is the factory fuel pump feed ? I have eliminated the fuel pump relay and all of the factory harness. There is a tan/white wire coming up to the firewall from the harness that goes to the tanks...- Steve87GMC
