The Wacker Neuson Fuel Cock is a genuine OEM component designed for the GV2500A, GV5000A, GV7000A, and GV7003A portable generator series, as well as the GS12Ai generator. As a direct factory replacement, this fuel cock meets the exact specifications Wacker Neuson requires to maintain consistent fuel delivery and safe engine shutoff. Sourced directly through authorized Wacker Neuson supply channels, part number is the correct choice when restoring your generator to full working order. Compatibility extends across multiple GV-series and 50Hz portable value generator configurations, making this one of the more broadly applicable fuel system components in the Wacker Neuson generator lineup.
Key Features
- OEM Fuel System Integrity — Manufactured to Wacker Neuson's exact flow and shutoff specifications, ensuring the valve opens and closes with the correct resistance and sealing pressure for this generator series.
- Drop-In Replacement — Matches the original mounting thread, port sizing, and lever orientation so installation connects directly without adaptation.
- Broad GV-Series Coverage — Fits GV2500A, GV5000A, GV7000A, GV5003A, and GV7003A models, plus GS12Ai and 50Hz Portable Value Generator configurations.
- Consistent Fuel Delivery — A fully functional fuel cock allows the engine to start quickly and run without fuel starvation; a worn or leaking valve can cause hard starts, erratic output, or uncontrolled fuel flow.
- Fuel System Safety — The fuel cock is the primary manual shutoff between the tank and carburetor. Using a correctly rated OEM valve reduces the risk of fuel leaks at the connection points during operation and storage.
The fuel cock is a manually operated valve that controls the flow of fuel from the tank to the carburetor. When opened, it allows fuel to pass through for normal engine operation; when closed, it cuts off the fuel supply for safe shutdown or storage. A degraded or leaking fuel cock can result in fuel seeping past the valve seat, creating a fire hazard and causing the engine to run poorly or fail to start — making timely replacement essential for both performance and safety.
