Generac Fuel Shutoff Valve 0H0406 Guardian Portable Generator OEM New.
Restore Positive Fuel Tank Isolation & Eliminate Gas Leaks: Genuine Generac 0H0406
Eliminate dangerous raw gasoline leaks, dripping petcocks, seized shutoff levers, and carburetor flooding on your Generac generator. This Genuine Generac Factory OEM Fuel Shutoff Valve (Part Number 0H0406 / 0H04060SRV) is the authentic manual fuel tank petcock engineered explicitly for Generac portable generators, GP-series units, and compact Guardian generator systems . Operating an emergency generator with a dripping or stuck fuel valve creates an immediate fire hazard around hot exhaust mufflers and allows fuel to leak into the crankcase during storage.
Manufactured to Generac's strict fuel-system safety and emissions standards, this commercial-grade valve is engineered to resist the corrosive effects of modern ethanol-blended fuels. It features a heavy-duty, fuel-resistant metal body with an internal Viton-grade elastomer seal to ensure a drip-free shutoff. Designed for positive fuel management, the rugged manual lever delivers an easy quarter-turn transition between open and closed positions, ensuring positive fuel isolation when transporting the generator in trailers or storing it between storm seasons. It comes complete with a precision barbed fuel line outlet for a tight, leak-free connection to standard small engine fuel hose.
This authentic factory replacement component is cataloged under Generac OEM Part Number 0H0406 (0H04060SRV / Valve, Fuel Shutoff / Tank Petcock / Fuel Petcock Assembly) .
Why This Genuine Generac 0H0406 OEM Fuel Valve is the Pro Standard:
100% Genuine Factory OEM Component: Manufactured directly to Generac engineering blueprints for leak-free sealing and precise thread/grommet fitment.
Ethanol-Resistant Internal Seals: High-grade elastomer internal seating resists swelling, cracking, and deterioration caused by modern E10 pump gas.
Positive Manual Flow Control: Smooth, positive-detent lever provides distinct ON/OFF positioning to prevent accidental weeping or vibration shut-offs under load.
Precision Barbed Hose Fitting: Ensures a tight, non-slip friction grip on 1/4" ID fuel lines, eliminating vapor leaks and fuel hose slip-off.
Emergency Preparedness Protection: Allows operators to run the carburetor completely dry before seasonal storage, protecting carburetor jets from varnish buildup.

🛠️ Pro-Maintenance Tip: Watch the "Carburetor Run-Dry & Tank Thread Sealing Secret!" Carburetor Run-Dry Storage Secret: The single best way to keep your generator ready for emergency storms is using this 0H0406 valve to store the machine properly! When you are done running the generator, do not turn the engine switch off immediately. Instead, flip this manual fuel valve to the OFF position while the generator is running and let the engine idle until it stalls from fuel starvation. This completely drains the carburetor float bowl and internal jets, preventing ethanol fuel from evaporating into green sticky varnish that clogs small passages during long storage periods. Thread Sealing Secret: If your tank utilizes a threaded bung rather than a rubber push grommet, wrap the male threads with fuel-rated yellow PTFE tape or brush with gasoline-resistant paste before installation. Never use standard white plumbing tape, as gasoline easily dissolves standard tape and washes shreds into your carburetor!
