The Wacker Neuson Fuel Tank is a genuine OEM fuel tank designed for the G100 and G120 generator series, including Custom T4i, Standard T4i, Cold Weather T4i, and Hertz T4i configurations. As a factory-sourced component, it meets the exact specifications set by Wacker Neuson for these machines, ensuring a direct, trouble-free installation. This part is confirmed to fit multiple variants across both the G100 and G120 generator lines, making it the right choice whether you're servicing a standard unit or a cold-weather-spec machine.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's exact material and dimensional specifications, so fuel capacity, mounting geometry, and connection points match the original tank precisely.
- Drop-In Installation — Engineered as a direct replacement that aligns with existing fuel line fittings, mounting brackets, and hardware on G100 and G120 platforms — no modifications to the machine needed.
- Broad G100 and G120 Compatibility — Fits Custom T4i, Standard T4i, Cold Weather T4i, and Hertz T4i variants across both the G100 and G120 generator series.
- Sustained Run Time — A properly sealed, structurally sound fuel tank maintains consistent fuel delivery to the engine, supporting uninterrupted generator output during extended operation.
- Fuel System Safety — A cracked or degraded fuel tank poses a serious fire and contamination risk on active job sites. Replacing a damaged tank with a genuine OEM unit restores the fuel system's integrity and keeps the machine operating safely.
The fuel tank stores and supplies the fuel needed to keep the generator engine running. It acts as the reservoir that feeds the carburetor or fuel injection system, and its condition directly affects run time, fuel efficiency, and engine performance. When a fuel tank cracks, warps, or develops a leak, it can starve the engine of fuel, create hazardous spills, or allow air into the fuel line — any of which can cause the generator to shut down unexpectedly or fail to start.
