The Wacker Neuson Carburetor Gasket is a genuine OEM carburetor gasket designed for the MDP3 75mm/3in diaphragm trash pump and PT3c water pump series. As a direct OEM replacement, this gasket is manufactured to the exact material and dimensional specifications required by Wacker Neuson, ensuring a proper seal between carburetor mating surfaces. Confirmed fitment covers the MDP3, MDP3X, MDP3-CE, MDP3-CN, and PT3G-c CE and PT3G-c CN model variants. When a carburetor gasket fails, fuel and air leaks compromise engine performance and starting reliability — replacing it with the correct OEM part restores proper operation quickly.
Key Features
- OEM Sealing Material — Manufactured to Wacker Neuson's exact material spec, delivering the compression and chemical resistance a carburetor gasket demands in a fuel-wetted environment.
- Drop-In Replacement — Matches the original bolt pattern and mating surface profile on MDP3 and PT3c series carburetors, so installation follows the standard service procedure without modification.
- Broad MDP3 and PT3c Compatibility — Fits MDP3, MDP3X, MDP3-CE, MDP3-CN, PT3G-c CE, and PT3G-c CN models, covering the full range of these 3-inch pump variants.
- Restores Correct Air-Fuel Seal — A compromised carburetor gasket allows unmetered air into the fuel circuit, causing hard starts, rough running, and loss of pump output. This OEM gasket re-establishes the correct sealed interface.
- Fuel System Integrity — A properly seated carburetor gasket prevents external fuel weepage at the carburetor joint, supporting safe operation of gasoline-powered pump equipment.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000409379 carries the full OEM traceability you need for fleet maintenance records and service documentation.
The carburetor gasket forms a critical seal between the carburetor body and its mating surface on the engine, keeping the air-fuel mixture contained within the intended fuel circuit. Without an intact gasket, uncontrolled air entry leans out the mixture, leading to hard starting, erratic idling, and reduced engine power — all of which directly affect pump output on the job. A worn or deteriorated gasket can also allow raw fuel to weep externally at the carburetor joint, making timely replacement both a performance and a safety priority.
