The Wacker Neuson Fuel Tank Cap is a genuine OEM fuel tank cap designed for a wide range of Wacker Neuson equipment including the MP12 and MP15 Single Direction Plates, MFS735 and BFS735c Floor Saws, and D3.5G2 and D3.5G3 Modular Internal Vibrators. As a factory-sourced component, it is manufactured to the exact specifications of the original part it replaces, ensuring a correct, trouble-free installation every time. Cross-reference part number against your model and serial number before ordering to confirm compatibility with your specific machine configuration.
Key Features
- Sealed to OEM Specification — Engineered to deliver the same thread engagement and seal compression as the original, preventing fuel vapors from escaping and contaminants from entering the tank.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this cap carries the same part number (5100058789) used by authorized service centers, so there's no guesswork on quality or fitment.
- Broad Model Coverage — A single part number covers the MP12 and MP15 plate compactor lines, MFS735 and BFS735c floor saws, and D3.5G2/D3.5G3 modular internal vibrators, making it a versatile stock item for mixed fleets.
- Fuel System Integrity — A properly sealing tank cap maintains the correct fuel system pressure balance, supporting consistent engine starts and smooth operation across all covered machines.
- Fire and Spill Risk Mitigation — A correctly fitting fuel cap is a critical safety component; a cracked, stripped, or poorly sealing cap can allow fuel leaks that create fire hazards and environmental violations on the worksite.
The fuel tank cap seals the opening of the fuel tank to keep fuel contained and prevent dirt, debris, and moisture from entering the fuel system. Many caps also incorporate a small vent that allows controlled airflow to equalize pressure as fuel is consumed, helping the engine draw fuel smoothly without vapor lock. When a fuel tank cap fails — whether through a cracked body, worn threads, or a degraded seal — it can cause fuel spillage, contamination of the fuel supply, hard starting, and potential safety hazards that take a machine out of service.
