Get double the value and ensure uninterrupted fuel flow with this 1-Piece Value Pack of 3-Way Vacuum Fuel Pump Petcocks. Specially engineered for standard GY6 4-stroke engines ranging from 50cc to 150cc, these valves use your engine’s natural vacuum pulse to safely draw fuel from the main tank down into the carburetor.

Constructed from a premium anti-corrosive zinc alloy, this inline assembly prevents dangerous fuel leaks, stops stalling issues, and ensures smooth throttle response during hot summer rides or heavy monsoon rains.

• Precise 3-Way Port Configuration: Built with three distinct, clearly engineered ports: One for Fuel Input, one for Fuel Output, and one for the Vacuum Line Link.

• Universal GY6 Compatibility: Direct plug-and-play fitment for almost all Chinese/Japanese style 50cc, 125cc, and 150cc scooter engines, mopeds, ATVs, quads, and dirt bikes.

• High-Response Diaphragm: Features a resilient internal polymer membrane that reacts immediately to minor engine vacuum pressure variations, keeping fuel pressure fully stabilized.
