Description

Replace a leaking or failed petcock with this GY6 125/150cc Automatic Vacuum Petcock. Chrome-plated zinc die-cast body with a round vacuum diaphragm housing, zinc-plated yellow chromate M16 hex nut, one downward-angled 6mm barbed fuel outlet, and one side-facing 6mm barbed vacuum port. A white translucent 66mm nylon mesh filter tube extends through the nut to catch sediment before it reaches the carburetor. Vacuum-operated: the internal diaphragm opens when the engine creates vacuum (cranking or running) and closes automatically when the engine stops, preventing carburetor flooding during storage.

Installation note: Connect the vacuum line to the side port and the fuel line to the lower barbed outlet. Always use a new 6mm fuel line and clamps at installation.
