Holley Safety Fuel Pressure Switches
It's always a good idea to place a safety switch in the circuit when installing an electric fuel pump. Holley safety fuel pressure switches will ensure the electric pump will not work unless the engine has oil pressure. It will prevent the pump from running in a situation where the motor may stall with the ignition on. Wiring the switch through the starter solenoid circuit energizes the pump on engine start-up. After the engine is running, the switch continues to provide power to the pump as long as there is oil pressure to keep the switch turned on.
