The Wacker Neuson Fuel Line is a genuine OEM component designed for HI 770 XHD indirect-fired diesel air heaters, including Arctic Bear XHD and HI770XHD series configurations. As a direct OEM replacement, is manufactured to the same specifications as the original part, ensuring a correct, trouble-free installation in your heater's fuel delivery system. This fuel line is the right choice when restoring a heater that has developed a leak, suffered a cracked line, or failed during cold-weather operation. Confirm your model number before ordering to ensure this line matches your specific HI 770 XHD configuration.
Key Features
- Genuine OEM Fuel Compatibility — Built to carry diesel fuel at the correct flow rate and pressure for the HI 770 XHD burner system, with material grade suited to resist fuel degradation and cold-temperature brittleness.
- Drop-In Replacement Fit — Matches original routing, length, and connection points on the HI 770 XHD platform, so installation aligns with the existing fuel system layout without rerouting or adapting fittings.
- HI 770 XHD Series Coverage — Fits multiple HI 770 XHD variants including Arctic Bear XHD, Arctic Bear XHD NS, and standard HI770XHD indirect air heater configurations across 1x16, 1x20, and 2x12 duct setups.
- Sustained Heat Output — A sound fuel line maintains consistent fuel delivery to the burner, supporting uninterrupted heat output on cold-weather jobsites where heater reliability is critical.
- Fuel System Safety — A cracked or failing fuel line poses a fire and leak risk in diesel-fired equipment. Replacing with a genuine OEM line restores the integrity of the fuel delivery path and keeps the heater operating within its designed safe parameters.
The fuel line is a critical link in the HI 770 XHD's diesel delivery system, routing fuel from the tank or filter assembly to the burner. It must maintain a sealed, leak-free connection under the vibration, heat cycling, and sub-freezing ambient conditions that indirect air heaters routinely encounter. When a fuel line cracks, hardens, or develops a leak, the heater may fail to ignite, produce inconsistent heat, or present a fire hazard — making timely replacement essential to both performance and safe operation.
