SureFit Engine Gas Shut Off Valve Kit with 1/4" Fuel Line & Clamps Universal Fit Lawn Mowers Tractors 504-00628

What It Is

This is a universal gas shut-off valve kit that lets you stop fuel flow to the carburetor for safe storage, transport, or carburetor service. It works on most walk-behind lawn mowers, tractors, and small engines with 1/4-inch fuel lines.

Fitment & Compatibility

Before buying, confirm your fuel line is 1/4-inch inner diameter (standard on most small engines). This kit includes the valve, two clamps, and a 1/4-inch fuel line, but if your existing line is a different size (e.g., 5/16-inch or 3/16-inch), you’ll need to measure or swap your own line. It fits most brands—Honda, Briggs & Stratton, Kohler, Tecumseh, Toro, Craftsman, and others—where the fuel line runs from the tank to the carburetor. No deck size or OEM part number needed; it’s a universal inline replacement.

Key Things to Know

• Installation is simple: Cut your existing fuel line, insert the valve in-line, and secure with the included clamps. No special tools needed.
• Quality is solid for the price: The brass valve resists corrosion, and the clamps are standard spring-style. Some users report the valve handle feels a bit light, but it holds tight.
• Common gotcha: If your engine has a primer bulb or gravity-fed system, make sure the valve doesn’t create a low point that traps air—mount it so the handle is easily accessible and the valve is oriented to let fuel flow downhill.
• Not for pressurized systems: This is for gravity-fed or low-pressure fuel systems (typical on mowers). Do not use on high-pressure fuel injection.

Should You Buy It

If you need a cheap, reliable way to shut off fuel for winter storage, carburetor cleaning, or safe transport, this kit is a no-brainer. It’s easy to install, fits most standard mowers, and at $6.95, it’s cheaper than replacing a gummed-up carburetor. Avoid it if your fuel line is larger than 1/4-inch or you need a valve for a pressurized system.
