Description
Vacuum Fuel Petcock for GY6 50cc and QMB139 Scooters
This petcock runs on engine vacuum and suits scooters that carry their gas tank up high. It opens and shuts on its own depending on vacuum, which keeps fuel moving reliably and helps stop the carburetor from flooding. It is a useful piece among the GY6 50cc scooter parts for keeping fuel flowing correctly while you ride.
Automatic Operation
Engine vacuum is what drives this petcock. Once the engine is running, the valve opens by itself and lets fuel through. When the engine shuts off, the valve closes, which cuts down on fuel leaking out and the flooding problems that can follow.
Specifications and Compatibility
The petcock has a coarse M14x1.00 thread, so it fits the fuel tanks of several models. A 5mm fuel outlet barb accepts standard fuel line, and a built-in 62mm filter tube helps keep debris out of the carburetor.
