The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI and HD series indirect-fired diesel air heaters, including the HI110HD D, HI110D, HI200D, HI200HD D, HI90, HI90HD, HI35, HD50, and HD70 models. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Correct fuel delivery is critical to consistent heater output, making an accurate-fit replacement essential for field reliability. Verify your model number before ordering to ensure compatibility with your specific unit.
Key Features
- Genuine OEM Fuel Delivery Integrity — Manufactured to the original internal diameter and wall thickness specifications, ensuring correct fuel flow rate to the burner assembly without restriction or leakage.
- Direct-Connect Replacement — Matches the original routing, end fittings, and length of the factory-installed line, allowing straightforward installation without modification to existing fuel system components.
- Broad HI and HD Series Coverage — Confirmed fitment across multiple Wacker Neuson indirect diesel heater models, including HI110HD D, HI110D, HI200D, HI200HD D, HI90, HI90HD, HI35, HD50, and HD70.
- Consistent Burner Performance — A fully intact fuel line maintains steady fuel pressure and flow to the burner, supporting stable ignition and full-rated heat output. A cracked or deteriorated line causes fuel starvation, weak flame, or heater shutdown.
- Fuel System Safety — Replacing a worn, cracked, or leaking fuel line with a genuine OEM part eliminates the risk of fuel weepage near ignition components — a critical concern in enclosed or partially enclosed workspaces where these heaters are commonly deployed.
The fuel line carries diesel from the supply tank to the burner assembly inside the heater. It must maintain a leak-free seal and an unobstructed internal passage to deliver consistent fuel volume at the pressure the burner requires. Over time, heat cycling and exposure to diesel can cause the line to harden, crack, or develop pinhole leaks — symptoms that typically show up as inconsistent ignition, reduced heat output, or visible fuel weepage around fittings. Replacing the line at the first sign of wear restores proper burner operation and prevents fuel from contacting hot surfaces inside the heater cabinet.
