The Wacker Neuson Fuel Pump is a genuine OEM component designed for the GDS5500G and GDS5500G LA generator series. Sourced directly from Wacker Neuson, this fuel pump meets the exact specifications of the original part — ensuring proper fuel delivery and consistent engine performance. It is a direct replacement for units running under part numbers and, covering both standard and LA configurations of the GDS5500G.
Key Features
- OEM Fuel Flow Accuracy — Engineered to deliver fuel at the correct pressure and volume for the GDS5500G engine, maintaining the combustion cycle the generator was designed around.
- Direct Drop-In Replacement — Matches the original mounting points, inlet and outlet connections, and port sizing for a straightforward swap with no alterations to fuel lines or fittings.
- Confirmed GDS5500G Fitment — Verified for GDS5500G (No-CE) and GDS5500G LA variants, covering both 5100079460 and 5100079461 machine configurations.
- Fuel System Integrity — A worn or failing fuel pump starves the engine of fuel, causing hard starts, rough running, or complete shutdown. Replacing it with the correct OEM part restores stable fuel supply and smooth operation.
- Fuel System Safety — As a critical fuel circuit component, using a genuine OEM pump helps prevent improper fuel delivery, leaks, and the associated hazards that come with a degraded or incompatible replacement.
The fuel pump is responsible for drawing fuel from the tank and delivering it to the carburetor or fuel injection system at the pressure and volume the engine requires. Without a properly functioning fuel pump, the engine receives an inconsistent or insufficient fuel supply, leading to performance issues ranging from hesitation and power loss to a complete failure to start. When a fuel pump wears out or fails, replacing it promptly with a correctly spec'd part is essential to restoring full generator output and protecting downstream fuel system components.
