Electric Fuel Pump: Operation
Pump is energized when ignition switch is in the start (cranking) position. After engine starts, pump receives current through oil pressure switch as long as there is approximately 3 psi of oil pressure. If, for any reason, oil pressure drops below 3 psi, contact is broken at the pressure switch and pump is deactivated.
NOTE:
Two fuses are involved in fuel pump operation: The 4 ampere in-line fuse located in the dark blue wire at front of cowl just above the master cylinder, and the 4 ampere "Gauges" fuse on the fuse block.
