The QAZAKY Fuel Tank Petcock Switch Valve is a high-quality replacement part designed for a broad range of off-road vehicles, generators, and small engines. This 3-position manual petcock features a simple yet effective hinge lever system, allowing you to easily control fuel flow with just a touch. The lever has three distinct positions: ON (fuel flowing with the lever pointing up), OFF (completely halting fuel flow when the lever is horizontal), and RESERVE (accessing the remaining fuel in the tank when levels are low).

Built to fit seamlessly into your existing fuel system, this petcock is compatible with a wide range of Yamaha ATV models, including the EF2000iSv2, EF2400iSHC, EF6300iSDE, ET600, ET650, and ET950 series, as well as generators like the EU1000i, EU2000i, and EU3000i. It also works with 50cc–125cc dirt bikes, pocket motorcycles, scooters, mopeds, quads, UTVs, and go-karts, making it a versatile upgrade for both recreational and utility use. The package includes everything needed for a straightforward replacement—one fuel valve petcock, one cleaning brush, one fuel filter, two fuel lines, and eight clamps—ensuring a hassle-free installation.

Crafted with durability in mind, this petcock is manufactured in an advanced factory with over a decade of experience, ensuring strict quality control. The silver finish not only adds a clean look but also helps resist corrosion, making it a reliable choice for frequent use. Whether you're maintaining your ATV, generator, or small engine, this petcock provides peace of mind with its robust construction and easy-to-use design.
