Key Features
- OEM Sealing Material Integrity — Manufactured from the same fuel-resistant gasket compound as the original, maintaining the compression and chemical resistance needed to hold a leak-free seal in a live fuel system.
- Drop-In Fitment for GDS5500G and D3.5GD2 Series — Matches the original bolt pattern and thickness, seating directly against the fuel pump mounting face without trimming or shimming.
- Confirmed Compatibility Across Multiple Variants — Fits GDS5500G No-CE, GDS5500G LA, and D3.5GD2 Modular Internal Vibrator configurations, covering both generator and vibrator platform applications.
- Fuel System Integrity Restored — A sound fuel pump gasket prevents fuel weeping and air ingestion that can cause hard starting, erratic engine speed, or fuel delivery failure under load.
- Fuel System Safety — A correctly sealed fuel pump gasket eliminates external fuel leaks at the pump mounting face, removing a potential ignition hazard on operating equipment.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100084436 carries the OEM part number for straightforward verification against your service manual or parts diagram.
The fuel pump gasket forms a sealed interface between the fuel pump body and the engine or pump housing it mounts to, preventing fuel from escaping the pressurized or vacuum side of the pump circuit. Without an effective seal, the pump can draw air rather than fuel, leading to lean running conditions, difficulty starting, or a complete loss of fuel delivery. A degraded or crushed gasket also creates an external fuel leak at the pump mounting face — a condition that worsens under heat cycling and should be addressed promptly to maintain safe operation.
