I'm about knee deep in wiring and need some advice on the fuel pump. I have a LS3 376/480 and Boyd's tank with the Stealth 340 fuel pump. I have decided to let the ECM control the fuel pump since the FFR wiring is too small for the pump requirements. My questions are, is there a problem with grounding the pump to the chassis back by the tank and how to incorporate the inertia switch into the circuit. On the FFR harness, if I'm reading it correctly, the inertia switch brakes the ground to the fuel pump relay control circuit, but only uses 14 ga. wire.
