Review on Sierra International Oil Pressure Sender (OP72533) - Enhanced SEO-friendly Product Name by Adam Taylor

My mechanical fuel pump was replaced with an electric fuel pump, but for fire safety reasons it was necessary to switch it off when the engine was switched off. This switch did it. A tee was added to the oil pressure line to allow both the gauge and this switch to work. The fuel pump operates with a wire from the starter motor via the NC switch terminal, but oil pressure is required after starting to continue to power the electric fuel pump via the NO switch terminal. The relay rating is 12V, so I can add an extra load without overloading this switch.
