The Wacker Neuson Fuel Tank is a genuine OEM Fuel Tank designed for the GPi3200, GPSi3200, GPi4300, and GPSi4300 portable inverter generator series. Sourced directly from Wacker Neuson, this is the same tank fitted at the factory — built to the exact dimensions, capacity, and material specifications of the original. It provides a direct, like-for-like replacement across multiple GPi and GPSi inverter generator models, covering both standard and super-silent configurations. When the original tank cracks, leaks, or is physically damaged, this OEM unit restores the generator to full operating condition without guesswork or adaptation.
Key Features
- OEM Fuel Containment Integrity — Manufactured to the same material grade and wall thickness as the original, ensuring leak-free sealing at all fittings and connection points.
- Direct-Fit Replacement — Matches the original mounting points, fuel outlet ports, and cap thread exactly, allowing straightforward installation on compatible GPi and GPSi generators.
- Broad GPi / GPSi Series Coverage — Confirmed fitment across GPi3200, GPSi3200, GPi4300, and GPSi4300 inverter generator models, covering multiple production configurations within those families.
- Consistent Fuel Delivery — A sound, undamaged tank maintains steady fuel supply to the carburetor; a cracked or leaking tank causes fuel starvation, rough running, or complete shutdown under load.
- Fuel System Safety — As a fuel-containing component, using a genuine OEM tank with correct vent and seal geometry prevents unintended fuel weepage and vapor buildup during operation and storage.
The fuel tank stores the generator's gasoline supply and feeds it to the carburetor at a controlled rate, keeping the engine running at a steady output. On inverter generators like the GPi and GPSi series, stable fuel delivery is especially critical because these units regulate engine speed dynamically to match the electrical load — any interruption in supply causes voltage fluctuations or unexpected shutdowns. A tank that has cracked, developed a pinhole, or has a damaged outlet fitting will either starve the engine of fuel or allow raw fuel to escape onto hot engine surfaces, both of which take the machine out of service and create a hazard on the worksite.
