The Wacker Neuson Fuel Tank is a genuine OEM component designed for the G100, G130, G150, and G180 series portable generators. As a direct OEM replacement sourced through authorized channels, this tank is manufactured to the same specifications as the original, ensuring correct capacity, mounting geometry, and fuel line connections. It is confirmed compatible across multiple G-series generator configurations, including standard, cold weather, and Tier 4 Final variants in both the G180 Mobile Generator and G180 600V Mobile Generator lines. When your existing tank is cracked, leaking, or contaminated, part number restores your generator to full operational condition without guesswork.
Key Features
- OEM-Grade Material Construction — Manufactured to the same fuel-resistant material and wall-thickness specification as the original tank, resisting fuel degradation and UV exposure over long service cycles.
- Direct Drop-In Replacement — Matches original mounting points, fuel outlet ports, and cap fitment on G-series generators so installation follows the factory service procedure without modification.
- Broad G-Series Compatibility — Fits G100, G130, G150, and G180 portable generators across standard, cold weather, and Tier 4 Final configurations, covering a wide range of Wacker Neuson GP equipment.
- Restores Full Runtime Capacity — A failed or leaking tank starves the engine of fuel and forces unplanned shutdowns; replacing it with 5100045509 returns the generator to its rated run time per fill.
- Fuel System Integrity — A properly sealed OEM tank eliminates the risk of fuel weeping near ignition sources — critical on generator equipment operating in enclosed or confined work areas.
The fuel tank stores and supplies diesel or gasoline to the generator engine, acting as the primary reservoir that feeds the fuel system throughout each operating cycle. A damaged, cracked, or heavily corroded tank compromises fuel delivery, causes unwanted leakage, and can introduce contaminants that damage downstream fuel system components such as the filter, pump, and carburetor or injectors. Replacing a worn tank promptly with a correctly specified OEM part keeps the fuel circuit sealed and the generator running at its rated output.
