Pressure Washer Fuel Solenoid | Fuel Shut Off Valve | Fuel Pump Coil

When a pressure washer fuel solenoid valve is energized, it opens to allow diesel fuel to flow into the burner fuel nozzle, where it is ignited by the electrodes. When power to the fuel shut off valve is cut, typically when the trigger gun is released, it stops the flow of diesel, preventing fuel being ported into the pressure washer burn chamber when no spark is present for ignition. It is important to be certain of the fuel solenoid voltage required, as incorrect voltage can cause the coil to burn out.
