Re: Electric fuel pump

Only extra thing I did on mine was ground the relay through the oil pressure sender and added a Duramax "lift pump" circuit. This gives me two major features:

1) The fuel pump runs for 5-6 seconds every time I turn the key on, but then stops running if it does not see oil pressure

2) The fuel pump stops in an accident or similar if the oil pressure drops (loses ground at the relay).
