The Wacker Neuson Fuel Cap is a genuine OEM component designed for the PD3B 75mm/3in diaphragm pump. Sourced directly from Wacker Neuson, this fuel cap is manufactured to the exact specifications of the original part, ensuring a proper seal and secure fit on the fuel tank. If your existing cap is cracked, missing, or no longer sealing correctly, replacing it with the correct OEM part keeps the fuel system functioning as intended. Verified fitment for the PD3B makes this a straightforward, confidence-inspiring replacement.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original thread pitch and gasket spec, ensuring the cap seats and seals as it did from the factory.
- Direct Bolt-On Replacement — Matches the original fuel tank filler neck on the PD3B for a drop-in swap with no fitting or modification.
- Verified Fitment for PD3B — Confirmed for the PD3B 75mm/3in diaphragm pump (machine number 5000006802).
- Fuel System Protection — A properly sealing fuel cap prevents contamination, fuel vapor loss, and siphoning — keeping the pump running cleanly between jobs.
- Fuel Safety Compliance — A failed or missing fuel cap creates a spill and vapor hazard; replacing it with the correct OEM cap restores safe fuel containment on the pump.
The fuel cap closes and seals the fuel tank filler opening on the PD3B diaphragm pump, preventing dirt, debris, and moisture from entering the fuel supply. It also contains fuel vapors and prevents spillage during transport or operation on uneven ground. When a fuel cap is cracked, stripped, or missing its internal gasket, it can allow contamination into the fuel system, leading to carburetor or engine issues, or create a fire and spill hazard on the worksite.
