The Wacker Neuson Fuel Tank Complete is a genuine OEM component designed for the GP3800A, GP5600A, and GP6600A generator series. Sourced directly from Wacker Neuson, this assembly meets the original build specification for these machines, ensuring the tank seats, seals, and connects exactly as the factory intended. If you're restoring fuel system integrity on any of these generators, the is the correct part to specify.
Key Features
- Genuine OEM Fuel Containment Integrity — Manufactured by Wacker Neuson to the same material and dimensional standards as the original, ensuring proper fuel retention and resistance to degradation from modern fuel blends.
- Complete Assembly, Ready to Install — Supplied as a complete tank unit, so all integrated fittings, mounts, and connections are included — no sourcing individual sub-components separately.
- Confirmed Fitment for GP-Series Generators — Verified for the GP3800A, GP5600A, and GP6600A, covering a range of Wacker Neuson portable generator models in one part number.
- Supports Consistent Fuel Delivery — A sound fuel tank keeps a steady, uninterrupted supply to the engine. A cracked, leaking, or degraded tank leads to fuel starvation, erratic output, and unplanned shutdowns on site.
- Fuel System Safety — A failed or compromised fuel tank presents a genuine fire and spillage hazard. Replacing with a genuine OEM assembly ensures the tank walls, seams, and fittings meet the original leak and pressure specifications.
The fuel tank stores and supplies the raw fuel your generator's engine needs to run. It works in combination with the fuel lines, filter, and carburetor to deliver a consistent flow from storage to combustion. When a fuel tank cracks, warps, or develops a leak — whether from impact, age, or fuel degradation — the result is fuel loss, potential fire risk, and an engine that will starve and shut down. Replacing the tank complete, rather than attempting patch repairs, is the only way to fully restore system integrity and safe operation.
