If you’ve ever had water in your diesel fuel, you know how quickly it can shut down your day. Water causes rough running, power loss, and can damage expensive injection components—problems that cost time and money when you’re trying to get work done. This water-in-fuel separator sensor gives you early warning when water starts accumulating in your fuel system, so you can address the issue before it becomes a bigger problem.
Key Features
- Electronic sensor alerts you the moment water accumulates in your fuel system
- Protects high-pressure injection components from water damage that costs thousands to repair
- Direct replacement sensor that connects to your existing wiring harness
- Built to handle the vibration and temperature extremes of farm equipment operation
- Quick installation gets you back to work without lengthy downtime
Built for Real Farm Work
This sensor works across John Deere’s lineup of mid-size utility tractors through their largest row-crop and four-wheel-drive machines. Whether you’re running a 6M series for hay operations, working with a 7R series for row crops, or operating an 8R or 9R series for large-scale farming, clean fuel is critical for reliable operation. These tractors handle everything from loader work to heavy tillage to harvest operations where fuel system problems can leave you stranded during the busiest times of the year.
Made to Last
Modern diesel injection systems operate at extremely high pressures with very tight tolerances, making them particularly vulnerable to water contamination. This sensor uses reliable electronic components that withstand the harsh environment of agricultural equipment while providing accurate water detection. The durable construction handles the constant vibration and temperature cycles that farm equipment endures.
Installation Notes
This sensor connects to your existing fuel system wiring and mounts directly to the water separator housing. When water accumulates beyond safe levels, the sensor triggers a warning light or message on your instrument panel. Check your operator’s manual for the specific location and drain procedure for your model, as different series may have slightly different setups.
