The Wacker Neuson Fuel Pump Gasket (0.3) is a genuine OEM component designed for GDS5500G generators and D3.5GD2 modular internal vibrators. Sourced directly from Wacker Neuson, this gasket matches the exact material grade and dimensional profile of the original part, ensuring a consistent, leak-free seal at the fuel pump interface. If you're servicing a GDS5500G or a D3.5GD2 unit, the is the correct replacement to bring the fuel system back to proper operating condition.
Key Features
- OEM-Spec Sealing Material — Manufactured to Wacker Neuson's original material specification, delivering the compression rating and chemical resistance required for a fuel pump gasket in a generator or vibrator application.
- Drop-In Fuel Pump Replacement — Sized and profiled to the original fuel pump mounting face, so the gasket seats cleanly without trimming or shimming during reinstallation.
- Confirmed Fitment — Compatible with GDS5500G (including LA variant) generators and D3.5GD2 modular internal vibrators, covering a range of Wacker Neuson generator and concrete equipment applications.
- Leak Prevention at the Source — A worn or degraded fuel pump gasket allows fuel seepage that disrupts fuel delivery and can lead to hard-start conditions or inconsistent engine output; this replacement restores the sealed interface.
- Fuel System Safety — Maintaining an intact fuel pump gasket is critical to preventing unintended fuel leakage around the pump — a genuine concern on generator and vibrator equipment operated in close-quarters or enclosed work environments.
A fuel pump gasket forms the sealing layer between the fuel pump body and its mounting surface on the engine, preventing fuel from escaping the pressurized circuit during pump operation. When the gasket degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to hold a seal, which can result in visible fuel weeping, air ingestion into the fuel line, or reduced pump output pressure. Replacing the gasket at the first sign of seepage keeps the fuel delivery circuit functioning as intended and prevents a minor wear item from developing into a more involved repair.
