The Wacker Neuson Tank Complete is a genuine OEM assembly designed for the PT4A and PT4A(I) series trash pumps. Sourced directly from Wacker Neuson, this is the same tank assembly supplied on the original machine — no guesswork on fit, materials, or configuration. It is confirmed compatible across PT4A and PT4A(I) model variants, making it the straightforward choice when the original tank is damaged, cracked, or due for replacement. Keeping the fuel system intact with the correct OEM assembly helps maintain consistent pump operation on the job.
Key Features
- OEM-Matched Tank Construction — Manufactured to the same material grade and dimensional tolerances as the original, ensuring proper sealing, capacity, and mounting alignment specific to PT4A series pumps.
- Complete Assembly, Ready to Install — Supplied as a complete tank unit so all integrated fittings and connections correspond directly to the pump's existing fuel system lines and mounts.
- Confirmed PT4A and PT4A(I) Fitment — Verified for PT4A and PT4A(I) series variants; use part number 5100039331 to confirm the correct match for your machine before ordering.
- Fuel System Integrity — A sound, properly fitted tank prevents fuel leaks and air ingestion that can cause hard starting, inconsistent running, or unplanned shutdowns on site.
- Fuel System Safety — As a fuel-carrying component, using the correct OEM tank assembly helps ensure secure connections and material compatibility, reducing the risk of leaks or fuel contamination.
The fuel tank on a trash pump stores and supplies fuel to the engine throughout operation. When the tank is cracked, warped, or developing leaks, the engine may be starved of fuel, run erratically, or shut down unexpectedly — and any fuel leak around machinery presents a genuine safety concern. Replacing a damaged tank with the correct complete assembly restores the sealed, stable fuel supply the engine needs to run at full capacity.
