The Wacker Neuson Fuel Cock Assembly is a genuine OEM component designed for ML-series Light Towers, ML-series Multifunction Floodlight Towers, and MG-series Portable Generators. As a direct OEM replacement, this assembly is sourced from Wacker Neuson and built to the exact specifications of the original part — no guesswork on compatibility. It fits a wide range of ML240, ML225, ML425, and ML440 light tower configurations as well as MG3 and MG5 portable generator models, making it one of the more versatile service parts in the Wacker Neuson lineup. Ordering by part number confirms you are getting the correct assembly for your machine.
Key Features
- OEM Fuel Flow Integrity — Manufactured to Wacker Neuson's original valve tolerances, ensuring consistent fuel shutoff and flow control without seepage or sticking.
- Direct-Swap Installation — Matches the original mounting points and fuel line connections on compatible machines, allowing straightforward removal and reinstallation during service.
- Broad ML and MG Series Fitment — Covers ML240, ML225, ML425, and ML440 Light Towers and Multifunction Floodlight Towers, plus MG3 and MG5 Portable Generators across multiple configurations.
- Dependable Fuel Shutoff — A properly functioning fuel cock assembly gives operators positive control over fuel supply, which is essential for safe storage, transport, and routine maintenance.
- Fuel System Safety — As part of the fuel delivery circuit, a worn or leaking cock assembly can create a fire hazard or cause uncontrolled fuel loss. Replacing it with a genuine OEM unit restores full shutoff reliability.
The fuel cock assembly serves as the manual shutoff valve in the machine's fuel supply line, controlling the flow of fuel from the tank to the engine. When open, it allows fuel to reach the carburetor or fuel system; when closed, it cuts off the supply entirely — a critical function during storage, transport, or maintenance. A deteriorated or faulty cock assembly can result in fuel leaks, failure to shut off fuel flow, or an inability to start the machine correctly, all of which compromise both safety and operational reliability.
