Wacker Neuson 5000115653 Fuel Transfer Pump

The Wacker Neuson Fuel Transfer Pump is a genuine OEM component designed for the G50, G70, and G85 series skid-mounted mobile generators. As a direct OEM replacement, this part is manufactured to the exact specifications of the original, ensuring proper fuel delivery and generator performance across the full range of compatible models. Fitment covers multiple configurations including standard skid-mounted and cold weather variants of the G50, G70, and G85 series. Verifying your model and machine number before ordering is the best way to confirm compatibility.

Key Features

• Genuine OEM Fuel Flow Accuracy — Manufactured to the original pump specification, ensuring correct fuel delivery rate and pressure for consistent generator output.
• Direct-Fit Replacement — Engineered to match the original mounting configuration and fuel line connections on G50, G70, and G85 series generators for a straightforward swap.
• Broad Series Coverage — Compatible with G50, G70, and G85 skid-mounted mobile generators across standard, cold weather, and alternate machine number configurations.
• Protects Engine and Fuel System Integrity — A functioning fuel transfer pump maintains steady fuel supply; a worn or failing pump can cause lean-running conditions, hard starts, or generator shutdown under load.
• Fuel System Safety — Using the correct OEM-spec pump ensures proper seal integrity and connection tolerances, reducing the risk of fuel leaks at the pump housing or line fittings.

The fuel transfer pump moves fuel from the onboard tank to the engine's fuel system, maintaining the steady, pressurized supply the engine needs to start reliably and run at rated load. On skid-mounted generators like the G50, G70, and G85 series, this pump operates continuously during use, making its condition critical to uptime. When the pump weakens or fails, symptoms typically include hard starting, power loss under load, or the generator shutting down unexpectedly — all signs that the pump is no longer delivering adequate fuel volume or pressure.
