The Wacker Neuson Fuel Cap is a genuine OEM component designed for RD12 series tandem rollers, PTS4V centrifugal trash pumps, and GPS9700 portable generators. As a direct OEM replacement, this fuel cap is manufactured to the same specifications as the original part, ensuring a proper seal and secure fit on the fuel tank. It is compatible with multiple machine configurations including standard, foldable ROPS, and pump variants across the RD12, PTS4V, and GPS9700 product lines.
Key Features
- Genuine OEM Seal Integrity — Manufactured to original equipment specifications, this fuel cap delivers the same tank-sealing performance as the part it replaces, preventing fuel vapor escape and contamination ingress.
- Cross-Platform Compatibility — A single part number that spans the RD12 tandem roller family, PTS4V trash pump variants, and GPS9700 generator series, making it a practical stocking item for mixed Wacker Neuson fleets.
- Direct Drop-In Replacement — Designed to thread directly onto the original fuel tank filler neck with no modification to the machine or cap assembly required.
- Fuel System Protection — A correctly sealing fuel cap keeps fuel free of dirt, debris, and water — contaminants that can clog fuel filters, damage injectors or carburetors, and cause hard-start or no-start conditions.
- Fuel Safety Compliance — A properly seated and sealing cap is essential for safe fuel handling and storage, preventing spills and fume release during transport and operation on active job sites.
The fuel cap seals the opening of the machine's fuel tank, preventing fuel from spilling during operation and stopping dirt, debris, and moisture from entering the fuel system. A damaged or missing cap can allow contamination that degrades fuel quality, accelerates filter and injector wear, and ultimately leads to poor engine performance or complete loss of function. Replacing a worn or cracked fuel cap promptly is one of the simplest ways to protect the fuel system and maintain consistent operation across your equipment.
