The Wacker Neuson 5100043862 is a genuine OEM Fuel Line Fitting designed for the GP-series portable generators, including the GP2500A, GP3800A, GP5600A, and GP6600A. As a direct-from-manufacturer component, it meets the exact tolerances and material specifications of the original part installed at the factory. This fitting is a straightforward swap for a failed or leaking original, restoring a secure, leak-free fuel line connection. Confirm your model number before ordering to ensure a correct match.
Key Features
- Genuine OEM Construction — Manufactured to the precise thread form, bore diameter, and material grade of the original fitting, ensuring a proper seal under fuel system pressure.
- Direct-Fit Replacement — Engineered to connect directly to the existing fuel line and carburetor or fuel system port with no rework of surrounding components.
- Broad GP-Series Compatibility — Verified fitment across the GP2500A, GP3800A, GP5600A, and GP6600A Wacker Neuson portable generator models.
- Leak-Free Fuel Delivery — A correctly seated fitting maintains consistent fuel flow to the engine; a cracked or loose fitting can cause fuel starvation, rough running, or dangerous fuel leaks.
- Fuel System Safety — Replacing a damaged fitting with a genuine OEM part eliminates the risk of fuel seepage at the connection point, which is a fire and safety hazard on a running generator.
The fuel line fitting is the connection point between the fuel line and the generator's carburetor or fuel system component, creating a sealed passage that allows gasoline to flow from the tank to the engine at the correct rate. A properly functioning fitting holds the fuel line firmly in place and prevents air ingestion or fuel leakage at the junction. When this fitting cracks, strips, or loosens — due to age, vibration, or overtightening — the generator may run erratically, refuse to start, or present a fuel leak that poses a serious fire risk during operation.
