This switch senses low oil pressure and shuts off your fuel pump.

Sierra's Oil Pressure Safety Shut-Off Switch features a 3-wire hookup to starter, pump and ignition. I/O and inboard units require a method to shut off the electronic fuel pump when the engine fails or is shut down. This switch senses the resulting low oil pressure and shuts the fuel pump off.
