The Wacker Neuson 5100012846 is a genuine OEM Fuel Gauge designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, RD18-100c, and their respective variants. As a direct OEM replacement, this gauge is built to the same specification as the original unit and installs directly into the instrument panel without adaptation. Wacker Neuson sources this part through their authorized supply chain, ensuring the calibration and sender compatibility match what the machine was built with. If your RD18's fuel gauge is reading inaccurately or has failed entirely, part number 5100012846 is the correct OEM replacement to restore accurate fuel monitoring.
Key Features
- OEM-Calibrated Readout — Matched to the RD18 series fuel sender unit for accurate, stable fuel level indication across the full gauge range.
- Direct Panel Replacement — Mounts into the original instrument panel cutout with the factory connector, requiring no wiring modifications or bracket adapters.
- Broad RD18 Series Coverage — Confirmed fitment across RD18-80, RD18-100, and RD18-100c variants, including US-spec and SE-designation models.
- Uninterrupted Fuel Awareness — A functioning gauge lets operators manage refueling schedules on long compaction runs, preventing unexpected shutdowns mid-pass on asphalt or soil.
- Fuel System Safety — Accurate fuel monitoring reduces the risk of running the machine dry, which can introduce air into the fuel system and complicate restarts on a live job.
The fuel gauge on an RD18 tandem roller displays the current fuel level by reading a signal from the tank-mounted sender unit and translating it into a visible readout on the operator panel. Operators rely on this gauge to plan refueling stops and avoid running the machine out of fuel during compaction passes. When the gauge fails or reads incorrectly, operators lose visibility into their fuel reserve, which can lead to unexpected shutdowns, air entrainment in the fuel system, and lost productivity on time-sensitive paving or soil compaction work.
