I have everything connected, but left the Fore fuel out of the tank so I could check and make sure the level sender and the pumps work prior to installing the tank. I turned the key to on position without starting car and nothing works. I mean the pumps did not make any noise and the fuel gauge just sits on empty when I move the fuel sender arm. I have the fuel level sender connected to the stock wiring and the GT pumps connected to the new dual FPDM harness from Lethal. Is there any way to check this stuff before installing the fuel tank?
