The Wacker Neuson Fuel Tube is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series, including diesel-powered configurations across multiple Arctic Bear XHD and HI770XHD variants. As a factory-sourced part, the matches the original specification for material grade, diameter, and routing path — ensuring a correct, secure connection within the machine's fuel delivery circuit. This Fuel Tube is compatible across a range of HI 770 XHD builds, covering 1x16, 1x20, and 2x12 duct configurations as well as Extra Heavy Duty Air Heater variants. When it's time to restore proper fuel flow to your indirect heater, replacing it with the correct OEM part is the most reliable path back to full output.
Key Features
- OEM-Matched Fuel Compatibility — Manufactured to the original material and dimensional spec, ensuring the tube handles diesel fuel without degradation or seepage over time.
- Direct-Fit Routing — Follows the factory fuel line path exactly, connecting to existing fittings without rerouting or adapter work.
- Broad HI 770 XHD Coverage — Fits multiple HI 770 XHD configurations, including Arctic Bear XHD, Arctic Bear XHD NS, and standard HI770XHD builds across 1x16, 1x20, and 2x12 duct setups.
- Consistent Burner Performance — A properly functioning fuel tube delivers steady, uninterrupted fuel flow to the burner assembly; a cracked or degraded tube starves the flame and causes inconsistent heat output or heater shutdown.
- Fuel System Integrity — In a diesel indirect heater, a compromised fuel tube is a fire and leak risk. Replacing with a genuine OEM part maintains safe, sealed fuel delivery in demanding cold-weather operating conditions.
The fuel tube carries diesel fuel from the supply side of the fuel system to the burner assembly inside the indirect air heater. It is a critical link in the combustion circuit — without a clean, unobstructed flow of fuel, the burner cannot sustain a consistent flame, which directly affects heat output and overall heater reliability. Over time, exposure to heat cycling, diesel fuel, and vibration can cause the tube to crack, harden, or develop leaks; when that happens, replacing it promptly restores safe and efficient heater operation.
