Re: 1968 Holiday Restoration w/pics
Ok this makes more sense. Not only is the fuel pump in circuit with oil psi switch but the pump is also hooked to the starter solenoid. I got this from the link that GLG fishing posted.
"ABYC standards require that the electric fuel pump turn off if the engine dies and the ignition switch is still turned on. It is common to power the fuel pump by the starter solenoid "I" terminal during cranking, then the pump is powered thru an oil pressure switch when the engine is running. If the pump runs all the time the ignition switch is turned on, you are asking for trouble. Just think, the engine dies from rich running because the needle and seat in the carb is stuck open. The ignition switch is left on for a bit and the pump fills the carb, intake etc.. with fuel. You go to resart and kaboom!!!!"
Makes more sense now that the starting solenoid is in play.
