Wacker Neuson 5000408526 Fuel Tank Cap

The Wacker Neuson is a genuine OEM fuel tank cap designed for a wide range of Wacker Neuson compaction plates, pumps, floor saws, and vibrator units including the MP12, MP15, MP20, ZEN-L, BPS1550c, BPS2050c, PT3c, and MFS735 series. As a factory-sourced component, it is manufactured to the exact specifications of the original part, ensuring a correct seal and secure thread engagement every time. This cap fits an extensive list of models sold across North American, CE, and CN markets, making it a versatile stock item for dealers, rental fleets, and service technicians. Confirm your model number against the fitment list before ordering to ensure compatibility.

Key Features

• OEM-Grade Seal Integrity — Manufactured to the exact thread pitch and sealing surface tolerances of the original cap, preventing fuel vapors from escaping and contaminants from entering the tank.
• Direct Thread-On Replacement — Installs directly onto the original tank filler neck with no modification to the tank or surrounding components.
• Broad Model Coverage — Fits MP12, MP15, MP20, ZEN-L 12/15/20, ZEN-C 20, BPS1550c, BPS2050c, PT3c, MDP3, MCP2, MCP3, MFS735, MFS1350, D3.5G2, D3.5G3, PG2c, and more across CE and CN variants.
• Fuel System Protection — A properly sealing tank cap maintains correct fuel delivery to the engine; a worn or cracked cap can allow debris ingestion or fuel loss, leading to poor engine performance or premature carburetor wear.
• Fuel Safety Compliance — Replacing a damaged or missing fuel tank cap with a genuine OEM unit helps prevent fuel spillage during transport and operation, reducing fire and vapor hazard on the worksite.
• Multi-Market Compatibility — Covers North American, CE, and CN market variants of the same model families under a single part number, simplifying parts inventory for service departments.

The fuel tank cap seals the filler opening on the equipment's fuel tank, keeping the fuel supply clean and contained during operation, transport, and storage. A secure, airtight cap prevents dirt, water, and debris from entering the fuel system, which is critical for protecting the carburetor and fuel lines on small-engine equipment. When a tank cap is cracked, stripped, or missing its seal, fuel can leak during handling, contaminants can enter the tank, and the engine may run erratically or sustain internal damage as a result.
