Description

There’s nothing more frustrating than running out of fuel because your gauge read wrong – especially when you’re baling hay or working a field miles from your fuel tank. If your fuel gauge is stuck on full, reading empty when you’ve got diesel, or bouncing around randomly, this replacement sender unit gets you back to accurate fuel level readings. No more guessing how much diesel you’ve got left when there’s work to finish.

What You’re Getting

Complete sender unit with float and resistance element that matches your original gauge calibration
Diesel-resistant construction that handles farm fuel conditions and temperature swings
Smooth, accurate readings throughout the tank’s range – no more dead spots or erratic bouncing
Proper resistance range calibrated specifically for John Deere 40 and 50 series gauge systems
Direct replacement that fits your tank opening without modifications or adapters

Built for Real Farm Work

This sender fits the reliable 40 and 50 series tractors that have been backbone machines on farms for decades. Whether you’re cultivating with a 2140, running a loader on a 1640, or baling with a 2750, knowing your fuel level prevents those expensive and embarrassing run-outs during critical operations. These workhorses burn through diesel when you’re getting things done, and accurate fuel monitoring helps you plan refueling stops efficiently.

Made to Last

Fuel senders take a beating from condensation, temperature changes, and constant vibration. This replacement uses quality components specifically chosen for diesel compatibility and farm conditions. The float mechanism moves freely without sticking, while the resistance element provides consistent signals that your gauge can trust season after season.

Installation Notes

Replace your sender when the tank is low to minimize fuel handling and contamination risk. Clean around the tank opening before removal, and note how the float arm is positioned for proper installation. Always use a new gasket to prevent leaks, and test the gauge through its full range after installation – it should read empty with the float down and full with the float up.
