Ok, so I have my fuel system installed and I am wiring the pumps. They will have voltage all the time and the ground will be selected to each pump as it is selected with a spdt switch. That switch is labeled "pump 1 and pump 2". That ground comes from my 5psi oil switch. So that the pump selected will only run when the engine is running and producing oil pressure. My second switch is to bypass all that and provide a ground to run the pumps when priming and starting and if the oil pressure switch was to fail. How would you label that switch?
pump bypass emergency pump fuel pump on ground use only pump bkup power Thanks Craig
