The Wacker Neuson Fuel Tube is a genuine OEM component designed for the HI 770 XHD series indirect-fired diesel air heaters, including Arctic Bear XHD and HI770XHD configurations. As a factory-sourced part, it is manufactured to the exact dimensions and material specifications required for proper fuel delivery in these heavy-duty heating units. This tube is a direct replacement for worn, cracked, or leaking fuel lines across the full range of HI 770 XHD Extra Heavy Duty Air Heater variants. Keeping this component in good condition is essential to maintaining consistent heat output and safe operation on cold-weather jobsites.
Key Features
- Genuine OEM Fuel-System Integrity — Manufactured by Wacker Neuson to exact material and dimensional tolerances, ensuring correct fuel flow rate and a leak-free connection within the HI 770 XHD fuel system.
- Direct-Fit Replacement — Engineered to connect at the same routing points as the original tube, allowing straightforward installation without modification to fuel line fittings or brackets.
- Broad HI 770 XHD Compatibility — Fits Arctic Bear XHD and multiple HI770XHD configurations, covering 2x12, 1x16, and 1x20 ducting setups as well as Extra Heavy Duty Air Heater variants.
- Consistent Fuel Delivery — A sound fuel tube maintains steady diesel supply to the burner, supporting reliable ignition and stable heat output in demanding cold-climate applications.
- Fuel System Safety — A cracked or deteriorated fuel tube can cause fuel leaks near the burner assembly, creating a fire hazard. Replacing with a genuine OEM part restores the integrity of the fuel circuit and reduces that risk.
The fuel tube routes diesel from the supply line to the burner assembly inside the indirect-fired air heater. It must maintain a sealed, unobstructed path under the pressures and temperatures generated during continuous heating operation. When this tube cracks, kinks, or develops a leak, fuel delivery becomes inconsistent — leading to poor ignition, uneven heat output, or a complete burner shutdown — and any fuel escaping near the heat exchanger creates a serious safety concern.
