Re: Hornets in South Bend, replacing a manual fuel pump with an electric one.

["Mark Price" <mprice@xxxxxxxxxx>]

Justin,
  You can get the oil pressure switch from Summitt.
I use one in my American although it is not currently connected.
What I did was run the + wire to a three way switch. Then one position of the switch sent current through the oil pressure switch to the pump and the other position bypassed the oil pressure switch.
Leaving the toggle in the center position killed the pump. Then when the car was started it would only run for a second or two and shut down. I had it that way as an antitheft device.
  I had the bypass feature because I did not quite trust the oil pressure switch and wanted to be able to bypass it to fill the carb bowl or in event the oil pressure switch failed.
