The Wacker Neuson is a genuine OEM Fuel Tank Cap designed for a range of Wacker Neuson vibratory plate compactors, centrifugal trash pumps, and the RS800V single drum vibratory roller. As a direct OEM part, it is manufactured to the exact tolerances and sealing specifications required by the original equipment, ensuring a proper fit on compatible WP1550VW, WP1550V, VPG165V, PT2V, and PT3V models. Sourcing the correct OEM cap means you get the right thread engagement, vent behavior, and seal compression for the fuel system on your specific machine — details that matter when equipment is running hard in the field. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- OEM Seal Integrity — Manufactured to the original sealing specification, maintaining correct fuel system pressure and preventing vapor loss or fuel spillage during operation.
- Direct Thread Match — Engineered to the exact thread pitch and filler neck diameter of the original tank, so the cap seats and locks without forcing or shimming.
- Broad Equipment Compatibility — Fits vibratory plate compactors (WP1550VW, WP1550V, VPG165V), centrifugal trash pumps (PT2V, PT3V), and the RS800V single drum vibratory roller.
- Fuel System Protection — A correctly sealing tank cap keeps debris, water, and contaminants out of the fuel supply — a worn or cracked cap can introduce contamination that degrades carburetor and engine performance over time.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the full OEM part number 5000086903 for accurate reordering and parts documentation.
The fuel tank cap seals the opening of the fuel tank, preventing fuel from spilling during transport and operation while keeping dirt, moisture, and debris out of the fuel supply. Most caps also incorporate a small vent to balance pressure inside the tank as fuel is consumed — a blocked or damaged cap can cause a vacuum lock that starves the engine of fuel, while a cap that no longer seals properly can allow contaminants into the system. Replacing a worn or damaged cap with the correct OEM part restores proper venting and contamination protection, keeping the fuel system functioning as designed.
