Key Features
- OEM Fuel System Integrity — Manufactured by Wacker Neuson to match the original cap's thread profile, seal geometry, and venting behavior, so fuel containment and pressure balance perform exactly as intended.
- Drop-In Thread Match — Engineered to the original filler neck thread specification, so the cap threads on cleanly without modification and seats flush against the tank opening.
- Broad Wacker Neuson Fitment — Confirmed fit across WP1540A, WP1550A, WPU1550A, WPU1550AW, VP1550AW, PT2A, HP50A, HP100A, BT24A, BT36A, and related series machines.
- Contamination Defense — A properly seated fuel filler cap keeps dirt, debris, and moisture out of the tank, protecting injectors and carburetors from wear-causing contamination.
- Fuel System Safety — A correctly sealing cap prevents fuel spillage and vapor escape during operation and transport, supporting safe handling on active job sites.
The fuel filler cap seals the opening of the machine's fuel tank, preventing fuel from spilling during operation, transport, or refueling and keeping contaminants such as dirt and water out of the fuel supply. Many caps also incorporate a small vent to allow controlled pressure equalization inside the tank — a function that supports consistent fuel delivery to the engine. When a filler cap is cracked, stripped, or missing its seal, fuel can leak or evaporate, debris can enter the tank and travel downstream to the carburetor or fuel injectors, and unsafe vapor buildup can occur.
