GOOFIT Universal Vacuum Switch with Internal Thread for Motorcycle/ATV Carburetors, Replacement Parts for Vacuum Diaphragm Fuel Valve

Universal internal thread: This product features an internal thread (internal spline) for direct connection to the standard external fuel outlet of the tank. It offers high adaptability, a secure fit, and excellent sealing, making it ideal for replacing and modifying universal systems. Automatic vacuum control: As a vacuum diaphragm fuel switch, it operates automatically and is controlled by the engine's intake pulsations. It automatically opens the fuel supply when the engine is running and closes it when the engine is off. This prevents fuel leaks at the carburetor and increases safety and ease of use. Wide vehicle compatibility: Thanks to its universal design, it is compatible with many motorcycles, off-road vehicles, ATVs, and small agricultural machines that have internal threads on the tank and use carburetors. It is particularly suitable for replacing worn or damaged original vacuum switches. Fixing fuel leaks and starting problems: It directly corrects faults such as fuel leaks after the engine is switched off, starting difficulties in cold weather and unstable fuel supply caused by diaphragm tears, aging seals or leaks in the vacuum lines, thus restoring the normal operation of the fuel system.
