The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI-series indirect-fired diesel air heaters, including the HI110HD D, HI110D, HI300D, HI200D, HI90HD, HI120, HI35, HD50, and HD70 models. Sourced directly from Wacker Neuson, this fuel line meets the exact specifications of the original part it replaces. It delivers a direct, verified fit for the models listed, so you can restore your heater to full operation without guesswork. Keep a spare on hand for fast turnaround during cold-weather work stoppages when your indirect heater is most critical.
Key Features
- Genuine OEM Fuel Integrity — Manufactured to Wacker Neuson's exact material and dimensional spec, ensuring the line handles diesel fuel pressure and temperature cycling without cracking, swelling, or seeping.
- Direct Connector Match — Engineered to connect at the same fittings and routing path as the original, allowing a clean swap without cutting, splicing, or adapting fittings.
- Broad HI-Series Compatibility — Confirmed fit across multiple indirect diesel heater models including the HI110D, HI110HD D, HI200D, HI300D, HI90HD, HI120, HI35, HD50, and HD70.
- Uninterrupted Fuel Delivery — A sound fuel line sustains steady diesel flow to the burner, maintaining consistent heat output. A cracked or blocked line causes erratic burner cycling, flame-outs, or complete shutdown.
- Fuel System Safety — A compromised fuel line on a diesel heater presents a fire and fume hazard on enclosed job sites. Replacing a degraded line with a genuine OEM part restores the integrity of the fuel circuit.
The fuel line carries diesel from the tank or fuel inlet to the burner assembly inside the indirect-fired heater. It must maintain a sealed, pressure-stable path so the burner receives a consistent, metered fuel supply for clean ignition and steady combustion. When the fuel line cracks, hardens with age, or develops a leak, fuel delivery becomes irregular — leading to hard starts, burner shutdowns, or unburned fuel odor that signals a safety concern. Replacing the line promptly keeps the heater operating at rated output and the fuel circuit properly sealed.
