The fuel cut-off valve is used as an external mechanism to stop the flow of gasoline from the fuel assembly to the engine to conserve fuel and maintain safe operation. If your device did not come with a cut-off valve, this is an easy install to give more control over the engine’s operation. When installing a fuel cut-off valve in your small gasoline engine, the first thing to note is the little arrow on the side of the valve. This indicates the direction that fuel will be flowing from the tank to the motor. Empty the fuel tank before proceeding with the repair. Remove the fuel line from the tank and cut the hose in two. Install properly sized hose clamps on either side of the cut and force the two ends of the valve into the severed line. Reattach the fuel lines and fill the tank. This fuel cut-off valve is compatible with a variety of gasoline-driven tools, including lawnmowers, generators, snowblowers, and chippers. Brands that use this OEM replacement part include Craftsman, Briggs & Stratton, Snapper, Simplicity, Toro, and Cub Cadet. This OEM part is sold individually.
