The Wacker Neuson Fuel Tank is a genuine OEM component designed for G100 and G120 series portable generators. As a factory-sourced part, it is manufactured to the exact specifications of the original, ensuring a direct fit across a wide range of G100 and G120 configurations including standard, cold weather, custom Tier 4i, mobile, and 600-volt switchable Tier 3 variants. Whether you are servicing a single unit or maintaining a fleet of generators, part number delivers the fit and integrity that keeps your equipment running as intended. Verify your model number before ordering to confirm compatibility with your specific machine configuration.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring correct capacity, mounting geometry, and fuel-line port placement specific to the G100/G120 generator platform.
- Drop-In Fitment — Engineered to match the original tank's mounting footprint and connection points, allowing straightforward removal and reinstallation without improvised modifications.
- Broad G100 and G120 Compatibility — Covers a wide range of configurations including standard skid, cold weather, Canada Transport, Custom T4i, mobile, and 600V switchable Tier 3 variants across both the G100 and G120 generator families.
- Fuel System Integrity — A properly sealed, undamaged tank maintains consistent fuel delivery to the engine, preventing air ingestion, fuel starvation, and the irregular output that a cracked or leaking tank can cause under load.
- Fuel Safety Compliance — As a primary fuel containment component, using a genuine OEM tank ensures the assembly meets the original leak-resistance and venting design of the machine — important for safe operation in enclosed or jobsite environments.
The fuel tank on a portable generator serves as the primary reservoir that stores and supplies diesel or gasoline to the engine during operation. It works in conjunction with the fuel line, filter, and carburetor or injection system to maintain a steady, controlled flow of fuel — any crack, warp, or seal failure in the tank can disrupt that flow and cause the generator to run rough, stall, or shut down entirely. On generator models used in cold-weather or high-demand environments, a compromised tank can also allow moisture ingress or pressure imbalances that accelerate fuel system wear downstream.
