The Wacker Neuson Tank Complete is a genuine OEM fuel tank assembly designed for a wide range of Wacker Neuson walk-behind concrete trowels, gasoline floor saws, trash pumps, and compaction equipment. As a direct OEM replacement, this tank is manufactured to the exact specifications of the original component, ensuring correct fitment and proper fuel delivery across all compatible models. Confirmed fitment includes the CT36 and CT48 walk-behind trowel series, the PT3A centrifugal trash pump, BFS 914 and BFS 940 floor saws, and select BPU reversible vibratory plate compactors. If you are servicing any of these machines, verifying part number against your serial number before ordering is always recommended.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring correct capacity, port placement, and connection geometry for proper fuel system function.
- Direct-Fit Replacement — Mounts in the original tank position with matching fuel line ports and mounting points, allowing straightforward removal and reinstallation without modification.
- Broad Model Coverage — Compatible with the CT36 and CT48 concrete trowel series, PT3A trash pumps, BFS 914AB, BFS 935AB, and BFS 940 floor saws, BPU 3050A, BPU 3750Ats, and BPU 4045A plate compactors, and additional Wacker Neuson equipment families.
- Fuel Integrity Maintained — A properly sealed and structurally sound tank prevents fuel leaks that can cause inconsistent engine performance, unexpected shutdowns, or fire hazards on the worksite.
- Fire and Fuel Safety — Replacing a cracked, leaking, or degraded tank with a genuine OEM unit is a critical safety measure; compromised fuel tanks are a leading cause of fuel-related hazards on powered equipment.
The fuel tank stores and supplies gasoline to the engine's carburetor or fuel system throughout operation. It is a sealed reservoir that must maintain structural integrity under vibration, heat cycling, and exposure to fuel and exhaust — conditions that are particularly demanding on concrete trowels, floor saws, and compaction equipment. When a tank cracks, warps, or develops a leak at a fitting, the engine may run lean, stall under load, or stop entirely; in more serious cases, fuel leaks create a significant fire risk. Replacing a worn or damaged tank with a correct OEM unit like the 5100000399 restores proper fuel supply and eliminates those risks.
