My 98 GT is running a KB 2.1 on a built motor. It has the odd year return style fuel system so I don't have any FPDMs. I'm upgrading my fuel tank (03/04 Cobra), pumps (2 Warlbro SSG342s) and fuel hat (Divsion X Dual Pump). I'm also upgrading the wiring with the Lethal Performance Dual Fuel Pump Return Style Wiring upgrade Kit where there are no instruction on how to hook it up on a non FPDM car. To my knowledge or what I've read, and correct me if I'm wrong is that the computer controls when the pump should kick in more fuel at high RPM and when to slow it down at low RPM, and this can be adjusted with a tuner correct? So if I install this wiring kit would that be bypassed, and would it throw any codes, If I can run this off what ever cable that feeds this info to the pump, where would it be located. Or should I just run the wiring off the CCRM, to the inertia cut off switch, to the pumps. Would I need 2 inertia switches?
