The Wacker Neuson Fuel Line is a genuine OEM component designed for the HI-series indirect-fired diesel air heaters, including the HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI90, HI90HD, HI120, HI35, HD50, HD70, and HDR-series direct-fired radiant heaters. Sourced directly from Wacker Neuson, this fuel line is manufactured to the exact material and dimensional specifications of the original part. Fitting a genuine OEM component ensures the fuel delivery path remains sealed, properly routed, and compatible with the heater's burner assembly. Cross-reference part number against your heater's model and serial number before ordering to confirm fitment.
Key Features
- Genuine OEM Material Integrity — Manufactured from fuel-resistant materials that match the original line's flexibility, wall thickness, and chemical compatibility with diesel fuel — critical for maintaining a leak-free connection under thermal cycling.
- Direct-Fit Replacement — Engineered to the original routing length and end dimensions, so the line connects directly to the existing fuel system fittings without cutting, splicing, or adapting.
- Broad HI-Series Compatibility — Confirmed fitment across multiple Wacker Neuson indirect and direct-fired diesel heater models, including HI35, HI90, HI90HD, HI110D, HI110HD D, HI120, HI200D, HI200HD D, HI300D, HD50, HD70, HDR45, and HDR155.
- Sustained Burner Performance — A sound fuel line delivers consistent fuel flow to the burner, supporting reliable heat output. A cracked, hardened, or leaking line starves the burner or causes fuel loss, reducing heating efficiency or shutting the unit down entirely.
- Fuel System Safety — Diesel fuel lines on heaters operate under heat and pressure cycles; using a correctly rated OEM line with proper end connections reduces the risk of fuel leaks near the burner assembly.
The fuel line carries diesel fuel from the tank or fuel filter assembly to the burner unit of the heater. It must maintain a continuous, sealed flow path to allow the burner to draw the correct volume of fuel for combustion and consistent heat output. Over time, exposure to heat, vibration, and diesel fuel causes fuel lines to harden, crack, or develop pinhole leaks — symptoms that show up as reduced heat output, fuel odor, or heater lockout faults. Replacing a degraded fuel line with a genuine Wacker Neuson part restores proper fuel delivery and keeps the heater operating as intended.
