GOOFIT Motorcycle Fuel Valve Switch, 104 mm Total Length, Universal Fuel Line Switch for Carburetors, for Scooters, Quads and Manual Fuel Valves.

Universal Standard Size: The standard design has an overall length (from threaded inlet to outlet) of 104 mm and is suitable for motorcycles, ATVs, scooters, and small ATVs that commonly use similar side-mounted fuel taps.

Three-Function Hand Switch: A classic three-position hand switch provides the following functions:

ON (Ride): Main fuel supply during normal driving.

OFF (Stop): Cuts off the fuel supply when stationary to increase safety and prevent carburetor overflow.

RES (Backup): Switches to the reserve fuel line (typically 0.5 to 1.5 liters of reserve fuel) when the main line is empty, allowing you to reach a gas station.

Robust Construction: The valve body is constructed from high-strength metal or engineering plastic, and the internal seals are fuel corrosion resistant, ensuring reliability, long-term tightness, and leak-free operation. Guaranteed.

Easy Installation and Replacement: This product is designed as a direct replacement for a worn or damaged fuel tap or switch with the same specification and function as the original vehicle. A standard gasket for easy fitting is usually included. Important Fitting and Compatibility Notes: Size and Interface Check (Key Steps): Length Measurement: Please remove your vehicle's original fuel switch and measure its overall length to ensure it is 104 mm. Also, measure the diameter and pitch of the mounting thread (e.g., M12 x 1.25) to ensure a proper fit. Fuel Line Connection: Check that the fuel line diameter at the inlet (to the tank) and outlet (to the carburetor) of this product matches the vehicle's original fuel line (typically 6 mm or 8 mm). Function and Vehicle Compatibility: This product is a manual mechanical switch, suitable for gravity-fed and carbureted vehicles. It is not compatible with vehicles with electronic fuel injection or vehicles requiring vacuum or electrical signal control. Before purchasing, please check the function of your vehicle's original switch (presence or absence of a "RES" position) and the installation angle to ensure optimal operation after replacement. Installation and Fuel Safety: Safety First: The fuel tank must be full or nearly empty before installation. Work must be carried out in a well-ventilated area and away from open flames. Sealing: Wrap an appropriate amount of fuel-specific sealing tape around the threads or apply liquid sealant (depending on the material) and then tighten to the specified torque to prevent leaks. Fuel Line Connections: Secure all fuel line connections with new clamps and carefully test for leaks after installation.
