The Wacker Neuson Fuel Gauge is a genuine OEM component designed for the HI750, HI900, and HI260 series indirect-fired air heaters. Sourced directly from Wacker Neuson, this fuel gauge delivers the exact fit and readout accuracy that operators depend on across diesel and gas-fired heater configurations. It is confirmed to fit a wide range of HI-series variants including skid-mounted, surge brake, and cold-weather models rated to -40°. Keep your heater running through the job with a gauge you can trust at a glance.
Key Features
- OEM-Accurate Calibration — Manufactured to Wacker Neuson specification, ensuring the gauge reads fuel level correctly across the full tank range — not just at the extremes.
- Direct-Fit Replacement — Engineered to install into the existing gauge port on HI-series heaters with no adaptation or rework to the fuel tank or mounting hardware.
- Broad HI-Series Compatibility — Fits HI750, HI900, and HI260 indirect-fired air heaters across diesel, gas, and dual-fuel configurations, including skid-mounted and mobile variants.
- Uninterrupted Heat Output — A functioning fuel gauge lets operators plan refueling before the tank runs dry, preventing unexpected heater shutdowns in cold-weather or concrete-curing operations.
- Fuel System Safety — Accurate fuel level monitoring reduces the risk of running the heater on a near-empty tank, which can introduce air into the fuel system and cause hard-restart or damage conditions.
A fuel gauge gives the operator a real-time visual reading of the remaining fuel level in the heater's tank. On indirect-fired air heaters like the HI750 and HI900 series, continuous operation is critical — a failed or inaccurate gauge can lead to unexpected fuel exhaustion, forcing a shutdown at the worst possible time during cold-weather heating or concrete curing. When the gauge sticks, reads falsely full, or stops responding altogether, it should be replaced promptly to restore confidence in fuel monitoring and keep refueling intervals on schedule.
