The Wacker Neuson Fuel Gauge is a genuine OEM component designed for the HI 300HD D, HI 400HD D, and HI 120HD indirect-fired diesel air heaters. Sourced directly from Wacker Neuson, this fuel gauge meets the exact specifications required for accurate fuel level monitoring on these machines. It is a direct-fit replacement for the original gauge, requiring no adaptation to install. Whether you are servicing a unit on an active heating job or restoring a machine after storage season, this part ensures the fuel monitoring system is back to full working order.
Key Features
- Accurate Fuel Level Indication: — Calibrated to display correct fuel levels across the operating range of the HI-series diesel heater tanks, so operators always have a true read on remaining runtime.
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original design specifications, ensuring the gauge matches the sender unit, dial range, and mounting interface of the factory-installed component.
- Direct-Fit Replacement: — Engineered to drop into the original gauge port on the HI 300HD D, HI 400HD D, and HI 120HD without recutting lines or modifying the instrument panel.
- Supports Uninterrupted Heater Operation: — A failed or inaccurate fuel gauge can lead to unexpected run-dry shutdowns on the worksite; replacing it restores operator confidence in fuel management.
- Fuel System Safety Awareness: — Maintaining a functioning fuel gauge is especially important on diesel-fired heating equipment where unmonitored low-fuel conditions can affect burner performance and safe shutdown cycles.
The fuel gauge on an indirect-fired air heater gives the operator a continuous visual read of diesel fuel remaining in the tank. Without a properly functioning gauge, there is no reliable way to anticipate refueling needs, which can result in unexpected burner shutdowns — a significant problem when the heater is maintaining cure temperatures on a concrete pour or keeping a worksite enclosure at a safe working temperature. A worn or damaged gauge that reads incorrectly can mislead operators into running the tank dry, which may also introduce air into the fuel system and require additional bleeding before the heater will restart.
