The PetrolScooter Vacuum Fuel Pump Cock Petcock is an essential replacement component designed for owners of Sukida and Jonway Chinese scooters who need to restore or maintain a reliable fuel delivery system. This part provides a precise fit for fuel tanks requiring a 14 mm connection, ensuring consistent fuel flow to the engine for optimal performance. While it is built for durability, users should verify their specific scooter model's port size before installation, as slight variations exist within the Chinese scooter category.

No, it is specifically designed for Sukida and Jonway models that utilize a 14 mm port. Always measure your existing port before purchase.
The outer nut diameter is 22 mm.
While often not required due to the built-in gasket, a small amount of fuel-resistant thread sealant can be used if you experience minor weeping.
The petcock uses engine vacuum to open an internal diaphragm, allowing fuel to flow only when the engine is cranking or running.
A standard adjustable wrench or a properly sized open-ended wrench is typically sufficient.
Ensure the gasket is properly seated and the nut is tightened firmly, but avoid overtightening which may damage the threads.
Verify that the vacuum line is securely attached to the petcock and has no cracks; without vacuum, the fuel valve will remain closed.
Clean the tank threads of any debris or old sealant before installing the new unit to ensure a smooth engagement.
Before installation, ensure your scooter is on a level surface and the fuel tank is drained to prevent spillage. Use a suitable wrench to unscrew the old unit, taking care not to damage the tank's threaded port. When installing, ensure the gasket is seated correctly to create a leak-proof seal. Compatibility is primarily for Chinese scooters branded as Sukida or Jonway that feature a 14 mm internal thread. Maintenance involves periodic inspection of the vacuum line attached to the petcock; if the line is cracked or brittle, replace it simultaneously to ensure the vacuum signal remains strong. Avoid overtightening the nut to prevent stripping the threads of the fuel tank.
