The Wacker Neuson is a genuine OEM Fuel Tank Vent Hose Assembly designed for the HI 770 XHD Indirect Air Heater in both the 1x16 Diesel and 2x12 Diesel (Arctic Bear XHD) configurations. As a direct OEM replacement, this assembly is sourced from Wacker Neuson and ensures the fuel tank venting system operates exactly as the heater was engineered to perform. Confirming your machine model against part number before ordering is the best way to guarantee a correct fit for your HI 770 XHD unit.
Key Features
- Genuine OEM Venting Integrity — Manufactured to Wacker Neuson's original specifications, ensuring correct internal diameter and material grade for diesel fuel vapor handling in indirect-fired heater applications.
- Direct Assembly Replacement — Supplied as a complete hose assembly with correct end fittings, allowing straightforward installation in the existing fuel tank vent routing without fabrication or adaptation.
- Confirmed HI 770 XHD Fitment — Compatible with both the HI 770 XHD 1x16 Diesel and the HI 770 XHD Arctic Bear XHD 2x12 Diesel indirect air heater variants.
- Fuel System Safety — A properly functioning tank vent hose prevents pressure buildup and vacuum lock in the fuel tank. A cracked, kinked, or blocked vent line can interrupt fuel delivery and create unsafe operating conditions in a diesel-fired heater.
- OEM Part Number Assurance — Ordering by the verified Wacker Neuson part number 5000166182 eliminates guesswork and helps avoid costly fitment errors on a climate-critical piece of equipment.
The fuel tank vent hose assembly allows the diesel fuel tank on the HI 770 XHD indirect air heater to breathe correctly as fuel is consumed and tank pressure changes with temperature. Without a functioning vent, negative pressure can build inside the tank and restrict fuel flow to the burner, causing the heater to shut down or fail to ignite. A damaged or degraded hose can also allow fuel vapors to escape into unintended areas, creating a hazard in enclosed jobsite environments where the heater is typically deployed.
