Oil Pressure safety switch for electric fuel pump

Never install any kind of electric fuel pump without a safety shut off of some kind. The left switch is a universal switch recommeded by the Carter Fuel Pump catalog. This switch disables the fuel pump when the engine stops. A three blade, low beam headlight plug fits those blades wonderfully. The long pipe is to allow the radiator hose to pass between the switches. It will be supported by a bracket bolted to the web beside the oil fill. The center tap is for a mechanical guage. The right sender is for the factory guage.
