When upgrading to an electric fuel pump, proper wiring can seem complicated. The Electric Fuel Pump Safety Switch is designed for Mustangs being upgraded from a mechanical fuel pump to an electric inline or in-tank fuel pump. Wiring is simplified and done so safely. The fuel pump will only run if there is a tach signal from the ignition so the pump will shut off if you are in an accident. In addition, the switch primes the pump for three seconds at initial key-on.

The fuel pump controller is a "must have" for any pony car equipped with an electric fuel pump. When the key is first turned on, the fuel pump operates for three seconds to prime the fuel system. This makes starting your Mustang fast and easy. After priming, the pump is only allowed to run when the engine is running. In the event of a crash, the fuel pump will turn off, stopping fuel flow. No plumbing into the oil lines or adding an extra priming button is needed. The Electric Fuel Pump Safety switch takes care of everything!
