What Is A Fuel Shutoff Solenoid
China Everlasting Parts Co.,Limited | Updated: Apr 27, 2017

A Fuel Shutoff Solenoid is an electronic switch that can automatically stop the fuel flow in the engine system. The valve is normally in the open position. A loss of electrical power to the valve or activating a switch in the vehicle closes the valve to stop fuel flow. The solenoid valve works by using a spring loaded plunger to press against the main fuel circuit passage and prevent fuel from entering the passage.

The fuel shutoff solenoid is located in the Fuel Pump, but the electronic switch is inside of the driver's compartment. Once the switch is activated, the flow of fuel stops, and the engine no longer operates. Many of these switches also have a manual override feature to shut off the fuel in the event of a power failure. The solenoids are useful in stopping fuel flow in the event of an accident.
