Description

Your fuel gauge sticking on empty, bouncing all over the place, or just plain not working? There’s nothing worse than running out of fuel in the middle of a field because you couldn’t trust what the gauge was telling you. Running out of fuel in the middle of a field is more than inconvenient – it’s potentially damaging to injection pumps and always happens at the worst time. This fuel sender unit gets your gauge working accurately again, so you always know exactly how much fuel you have left in the tank.

What You’re Getting

Modern materials that resist today’s fuel formulations while maintaining the correct resistance values your vintage gauge requires. The robust float arm and resistance strip provide years of accurate readings, even with the sloshing and vibration of field work.
Resistance range that matches your tractor’s gauge requirements – critical for accurate readings. Float arm length and travel are calibrated for these specific tank dimensions. The mounting pattern fits exactly without modifications.
Replacement that addresses the common failure modes from corrosion, varnish buildup, and mechanical wear
Direct replacement design that installs without modifications or adapters

Built for Real Farm Work

This sender works with Fiat tractors in the 66 Series models 55-66, 60-66, 65-66, 70-66, and 80-66, plus the Classique Series including 446, 466, 566, 666, and 766. These are serious working tractors used for everything from cultivating and planting to hay operations and loader work around the farm.

Made to Last

These sender units commonly fail from contamination, corrosion, or simple wear after years of float arm movement. The result is either no reading, incorrect readings, or that annoying bounce that makes the gauge useless. This replacement is built to handle the challenges that come with farm life and provide reliable fuel monitoring for years.

Installation Notes

Drain tank completely before removal. Work in well-ventilated area away from ignition sources. Clean tank opening area to prevent debris from falling in during installation. Remove carefully to avoid bending the float arm. Compare new and old units to verify correct replacement. Check float arm movement through full range – it must move freely without binding. Install with new sealing gasket to prevent leaks.
