The Wacker Neuson Fuel Tank Cap is a genuine OEM fuel tank cap designed for a wide range of Wacker Neuson compaction plates, reversible plates, floor saws, modular internal vibrators, and fire pumps — including the MP15, MP70, MPU 29, MFS12, MFS14, MFSX14, MD3.5, MFP1.5, and MFP2 series. Sourced directly from Wacker Neuson, this cap is an exact match for the original part fitted at the factory. It installs directly onto the fuel tank filler neck without any adaptation, ensuring a secure, leak-free seal from day one.
Key Features
- OEM-Certified Fuel System Integrity — Manufactured to Wacker Neuson's exact seal and venting specifications, this cap maintains correct tank pressure and prevents fuel contamination — critical for small-engine reliability.
- Direct OEM Drop-In Replacement — Engineered to the same thread pitch and cap diameter as the original, part 5000403696 threads on cleanly with no fitting issues.
- Broad Cross-Series Compatibility — Fits MP15, MP70, MPU 29, MFS12, MFS14, MFSX14, MD3.5, MFP1.5, and MFP2 series machines, making it a practical stock item for mixed Wacker Neuson fleets.
- Leak and Spill Prevention — A properly sealing fuel tank cap keeps fuel where it belongs — a worn or missing cap can cause fuel loss, vapor release, and engine starvation under load.
- Fuel System Safety — A correctly fitted cap is the first line of defense against fuel spillage and ignition risk, especially on fire pumps and saw equipment operating near flammable materials.
The fuel tank cap seals the filler opening on the machine's fuel tank, keeping fuel secure during transport, storage, and operation. It typically incorporates a venting mechanism that allows controlled pressure equalization, preventing vacuum lock that would starve the engine of fuel. When a fuel tank cap is cracked, cross-threaded, or missing its seal, the result can range from fuel evaporation and contamination to engine run-on issues or complete fuel starvation — all of which interrupt work and increase operating cost.
