The Wacker Neuson Fuel Tank is a genuine OEM component designed for the HI 400HD D Indirect Air Heater and HI 120HD Indirect Air Heater. As a direct OEM part, it is manufactured to the exact specifications of the original, ensuring a correct, hassle-free installation with no guesswork on fit or function. If your heater is running dry due to a cracked, leaking, or damaged tank, the is the verified replacement to restore your machine to full operation. Cross-reference your model number before ordering to confirm compatibility with your specific unit.
Key Features
- OEM Fuel Containment Integrity — Manufactured to the original tank geometry and material specification, ensuring the same leak-free seal and capacity as the factory-installed unit.
- Direct-Fit Replacement — Designed to mount using the original attachment points and fuel line connections on the HI 400HD D and HI 120HD, so installation aligns with the existing hardware without reworking the fuel system.
- Verified Fitment — Confirmed for the HI 400HD D Indirect Air Heater and HI 120HD Indirect Air Heater model lines, giving you confidence you are ordering the correct part the first time.
- Sustained Heater Output — A fully intact fuel tank maintains consistent fuel delivery to the burner, keeping the heater running at rated heat output — a failed or leaking tank starves the burner and shuts down the unit.
- Fuel System Safety — A compromised fuel tank on a direct-fired heater poses a genuine fire and leak hazard on site; replacing it with a genuine OEM tank restores proper containment and keeps the machine operating within its designed safety parameters.
The fuel tank stores and supplies the diesel fuel that powers the burner in an indirect air heater. It feeds fuel at the correct rate to the combustion chamber, which in turn heats the air distributed through the ductwork on a jobsite. When the tank cracks, warps, or develops a leak — whether from impact, age, or freeze damage — fuel delivery becomes inconsistent or stops entirely, shutting the heater down and leaving workers without heat in cold-weather conditions. Replacing a damaged tank promptly with a correctly specified part restores safe, uninterrupted heater operation.
