Vacuum Actuated Fuel Petcock

Fits most four stroke Chinese scooters 50-150cc

Common on GY6 engines · Vacuum operated

📋 Overview

This vacuum actuated fuel petcock mounts on the gas tank bottom and fits most four stroke Chinese scooters from 50cc to 150cc. It is the most common fuel valve found on GY6 engines.

🔧 How it works:

Vacuum actuated petcocks use engine vacuum to control fuel flow. When the engine runs, vacuum opens the diaphragm, allowing fuel to flow to the carburetor. When the engine stops, vacuum disappears and the valve closes, shutting off fuel.

This design prevents fuel from continuing to flow when the engine is off, avoiding carburetor flooding and engine flooding.

🔍 Fuel Flow Troubleshooting

If you are having gas flow problems you should look at all gas and air lines plus this valve. Here's a simple test to check if it's working:

✅ How to test your fuel petcock:

Remove the main gas line from the carburetor
Try to start the scooter (this will create vacuum)
Observe if gas flows out freely
If gas comes out freely: Petcock is working, problem may be elsewhere
If no gas or weak flow: Replace the petcock

📌 Note: Common issues with vacuum petcocks include ruptured diaphragms, leaking or clogged vacuum lines. Ensure vacuum line is properly connected when performing the test.

🏍️ Applications

Most four stroke Chinese scooters 50-150cc
GY6 engine series (50cc, 125cc, 150cc)
Other small displacement scooters using vacuum petcocks

✅ Universal replacement: This vacuum petcock is the standard equipment on GY6 and similar engines. Direct replacement for worn or failed fuel valves. Solves fuel delivery issues and prevents fuel flow when engine is off.

⚠️ Please verify your scooter uses a vacuum-operated petcock rather than a gravity-feed type before ordering. This valve fits most 50-150cc four stroke Chinese scooters with GY6 and similar engines. Ensure proper vacuum line connection during installation.
