Gsab Posted February 18, 2021 Report Share Posted February 18, 2021 Link G4 Thunder. I`m finding that the fuel pump prime will prime the pump set to 5 seconds but after the 2 or 3rd attempt it will not switch the pump relay. I need to crank 3 or 4 times as I am running a mechanical main pump and simply use the lift pump to get fuel up front. Is this normal?
