Fix Fuel Leaks, Engine Flooding & Hard Starting Issues
This fuel shut-off valve (petcock) controls gasoline flow from the tank to the carburetor in gravity-fed generator systems. It helps stop fuel leaks, prevent carburetor flooding, and protect your engine during storage.
If your generator is leaking gas, flooding, or struggling to start, a worn or clogged fuel valve is often the cause. Replacing the valve can restore proper fuel flow and prevent further engine issues.
Compatible with Generac generators, including:
5500
5550
8550
Model No. 01646
This valve features manual ON/OFF control, an integrated pickup tube with mesh filter screen, and a rubber grommet connection for a secure tank seal. The 90-degree outlet allows efficient fuel line routing, while the barbed connector ensures a tight hose fit.
