The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI110HD D, HI110D, HI200D, HI200HD D, HDR115, HD70, and HI35 series indirect-fired air heaters and direct-fired radiant heaters. As a factory-sourced part, the is manufactured to the exact material grade and dimensional tolerances specified for these units, ensuring a correct, leak-free connection within the fuel delivery circuit. This line is confirmed compatible across multiple Wacker Neuson diesel heater configurations, making it the right choice when restoring fuel system integrity on any of the listed models. When your heater is losing heat output or showing signs of fuel delivery issues, replacing the fuel line with the correct OEM part gets the unit back to full, consistent operation.
Key Features
- OEM-Grade Fuel Compatibility — Manufactured from materials rated for diesel fuel exposure, resisting softening, cracking, or swelling that can occur with non-spec lines over time.
- Exact-Fit Fuel System Connection — Engineered to match the original routing, end fittings, and diameter of the factory line, seating correctly without modification to barbs, clamps, or connectors.
- Broad Heater Series Coverage — Fits HI110HD D, HI110D, HI200D, HI200HD D, HDR115, HD70, and HI35 heaters, covering a wide range of Wacker Neuson diesel and direct-fired heating equipment.
- Consistent Fuel Delivery — A sound fuel line maintains steady flow to the burner, supporting reliable ignition and full heat output — a degraded line can starve the burner, cause misfires, or produce uneven heating.
- Fuel System Safety — Cracks, brittleness, or loose connections in a heater fuel line present a serious leak and fire risk; replacing with a genuine OEM line restores the integrity of a safety-critical circuit.
The fuel line carries diesel fuel from the tank or fuel inlet to the burner assembly inside the heater. It is a critical link in the fuel delivery system — without a sound, properly sealed line, the burner cannot receive a consistent fuel supply, leading to ignition failures, reduced heat output, or complete shutdown. Over time, heat cycling, fuel exposure, and vibration can cause the line to harden, crack, or develop leaks at the connection points; replacing it promptly with a correctly spec'd part like the Wacker Neuson 5000186810 restores safe, full-output heater operation.
