The Wacker Neuson Fuel Level Sensor is a genuine OEM component designed for the E1250S, E1250P, and HSH380S series hydronic surface heaters. As a factory-sourced part, the matches the original sensor specification exactly, ensuring correct signal output and a direct drop-in installation with no adaptation needed. Confirmed fitment covers the E1250S, E1250P Premium Diesel, E1250P Premium LP/NG, HSH380S, and HSH380S Diesel with Generator configurations.
Key Features
- Accurate Signal Output: — Engineered to deliver the correct resistance range for the fuel gauge circuit, so operators get an honest, real-time read of tank level — not a stuck or erratic needle.
- Genuine OEM Sourcing: — Sourced directly from Wacker Neuson, this sensor is built to the same specification as the part that left the factory, with no re-engineering or substitution of materials.
- Direct-Fit Installation: — Designed to connect to the existing wiring harness and tank port on covered heater models, allowing a straightforward swap during routine service or breakdown repair.
- Broad Heater Family Coverage: — A single part number covers the E1250S, E1250P (Diesel and LP/NG), HSH380S, and HSH380S Diesel with Generator — consolidating your parts order across multiple units on site.
- Prevents Unexpected Fuel Runout: — A failed or inaccurate sensor can cause the heater to shut down mid-cycle from fuel starvation, disrupting concrete curing or cold-weather heating schedules. Replacing a faulty sensor keeps fuel monitoring dependable.
- Fuel System Safety: — Accurate fuel level monitoring is a core part of safe heater operation; a correctly functioning sensor helps operators manage refueling intervals and avoid dry-running conditions that can stress the fuel system.
The fuel level sensor monitors the quantity of fuel remaining in the heater's tank and transmits that information to the operator display or gauge. It typically uses a float-and-resistor mechanism — as the fuel level drops, the float position changes resistance, which the gauge reads as a fuel level. When the sensor fails or drifts out of calibration, readings become unreliable, leaving operators unable to judge when a refuel is needed. On hydronic surface heaters like the E1250S and HSH380S — which are often running unattended during overnight concrete curing cycles — an accurate fuel level reading is essential to keeping heat output consistent through the full cure window.
