The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI series indirect-fired diesel air heaters, including the HI 120HD, HI 200HD D, HI 300HD D, and HI 400HD D. Sourced directly from Wacker Neuson, this fuel line matches the original part exactly — same material, same dimensions, same routing configuration. It is a direct fit for the models listed above, requiring no modification to install. Keep a spare on hand and you are ready to turn around a fuel delivery issue fast and get your heater back to full output.
Key Features
- Genuine OEM Fuel Delivery Integrity — Manufactured to Wacker Neuson's original material and pressure specifications, ensuring consistent fuel flow to the burner assembly without seeping or cracking under diesel fuel exposure.
- Direct-Fit Replacement — Matches the original routing path and connection points on the HI series heater fuel system, dropping in without rerouting or adapting fittings.
- Broad HI Series Compatibility — Fits the HI 120HD, HI 200HD D, HI 300HD D, and HI 400HD D indirect-fired diesel air heaters, covering the full HD range of Wacker Neuson's indirect heater lineup.
- Sustained Burner Performance — A fuel line in good condition maintains steady, uninterrupted fuel delivery to the burner, which is essential for consistent heat output and efficient fuel consumption on the jobsite.
- Fuel System Safety — A cracked or deteriorated fuel line is a fire and leak hazard on any diesel-fired heater. Replacing 5000183918 at the first sign of wear keeps the fuel system sealed and the heater operating safely.
The fuel line carries diesel from the tank to the burner assembly inside the indirect-fired heater, maintaining a sealed, pressurized path that the fuel injection system depends on for clean combustion. If the line cracks, hardens, or develops a leak, fuel delivery becomes inconsistent, leading to weak heat output, hard starting, or a complete burner shutdown — and introducing a fire risk in any enclosed or semi-enclosed workspace. Replacing a worn fuel line with the correct OEM part restores the integrity of the entire fuel circuit and brings the heater back to its rated heating capacity.
