The Wacker Neuson Fuel Injection Pump is a genuine OEM component designed for the G155 skid-mounted mobile generator. Sourced directly through Wacker Neuson's authorized parts program, this pump is built to the exact specifications of the original unit installed at the factory. Correct fuel injection is critical to generator output and engine longevity, making this a part where using the right component matters — the is the verified direct replacement for the G155 platform.
Key Features
- Genuine OEM Metering Accuracy — Calibrated to deliver precise fuel volumes at the correct pressure and timing intervals required by the G155 engine, maintaining rated power output.
- Direct-Fit Replacement — Engineered to bolt into the existing fuel system mounting points on the G155 skid-mounted generator with no modifications to fuel lines or brackets.
- G155 Generator Fitment Confirmed — Verified for the G155 Mobile Generator Skid Mounted platform, so you can order with confidence knowing this is the correct part for your machine.
- Protects Engine from Fuel Starvation and Over-Fueling — A correctly functioning injection pump keeps combustion consistent; a worn or failing pump causes hard starts, rough running, excessive smoke, and accelerated engine wear.
- Fuel System Integrity — As a critical fuel-delivery component, using the genuine OEM part ensures correct sealing and pressure retention, reducing the risk of fuel leaks or uncontrolled injection events.
The fuel injection pump is responsible for drawing diesel fuel from the tank and delivering it to the injectors at precisely controlled pressure and timing. On a generator like the G155, consistent fuel delivery is what keeps engine speed stable under changing electrical loads — any variation in pump output shows up immediately as voltage fluctuation or power loss. When the injection pump wears out or fails, symptoms typically include difficult cold starting, uneven idle, black or white exhaust smoke, and a progressive loss of rated generator output.
