DONT run it dry for more than a few seconds!!! Most electric vane pumps are
cooled by the fuel flow and dont like pumping air.

You can wire in a neat fuel pump shutoff using a 96-2000 chevy vortec 5.7 truck oil pressure switch...it has a circuit that opens when the oil pressure dies. If you wire a relay coil thru the switch, when the engine is off or the oil pressure dies, the fuel pump is shut off. You also need a hot feed on the start lead of your ignition switch to energize the pump when you are cranking.
