The Wacker Neuson Fuel Pump is a genuine OEM component designed for the HI 770 XHD series indirect-fired diesel air heaters. Sourced directly from Wacker Neuson, this fuel pump is an exact match for the original part installed at the factory, ensuring a correct, straightforward swap with no guesswork on compatibility. It fits across multiple HI 770 XHD configurations, including the Arctic Bear XHD, Arctic Bear XHD NS, and standard HI 770 XHD Extra Heavy Duty variants. When your heater's fuel pump fails, replacing it with the correct OEM part — Wacker Neuson — restores reliable fuel delivery and gets your heating unit back to full operating capacity.
Key Features
- Genuine OEM Fuel Delivery Accuracy — Matched to the exact flow rate and pressure spec of the original pump, ensuring consistent fuel delivery to the burner assembly without calibration adjustments.
- Direct-Fit Replacement — Engineered to the same mounting configuration and connection points as the factory-installed pump, allowing a clean drop-in installation on HI 770 XHD units.
- Broad HI 770 XHD Compatibility — Fits Arctic Bear XHD, Arctic Bear XHD NS, and multiple Extra Heavy Duty HI 770 XHD configurations across various tank and duct arrangements.
- Sustained Burner Performance — A properly functioning fuel pump maintains steady combustion in the burner chamber; a worn or failing pump causes inconsistent heat output, hard starts, or complete heater shutdown.
- Fuel System Safety — Correct fuel pump operation prevents under- or over-fueling conditions that can compromise combustion safety on diesel indirect-fired heating equipment.
The fuel pump in an indirect-fired diesel air heater is responsible for drawing diesel fuel from the tank and delivering it at the correct pressure to the burner nozzle. Without a properly functioning pump, the burner cannot atomize fuel correctly, leading to weak ignition, unstable flame, or a complete failure to fire. On heavy-duty units like the HI 770 XHD — built for demanding cold-weather jobsite applications — a failed fuel pump means the heater is offline entirely, making a fast, accurate replacement critical.
