Description

When your fuel gauge starts acting up—bouncing around, reading empty when you know there’s fuel, or staying pegged full—chances are your fuel tank sending unit has given up the ghost. These vintage International Harvester tractors were workhorses in their day, but their fuel senders weren’t built to last forever. A failing sender doesn’t just make you guess how much fuel you have left; it can leave you stranded in the middle of a field job when you thought you had plenty of diesel.

What You’re Getting

Proper resistance range of 32 ohm full to 244 ohm empty—exactly what your Stewart Warner gauge needs
Durable float assembly that won’t sink or get waterlogged like the originals often did
Corrosion-resistant construction that handles today’s fuel formulations and moisture
Direct replacement design that mounts in your existing fuel tank opening

Built for Real Farm Work

This sending unit works across a wide range of International Harvester’s most popular models from the vintage era—everything from the smaller utility tractors like the 560 and 660 up through the big row-crop machines like the 1066 and 1206. These tractors spent their lives doing the heavy lifting on farms across America, from plowing and planting to harvest and hay work.

Made to Last

The original senders in these tractors often failed because the float would take on fuel or the resistance strip would corrode. This replacement uses modern materials that resist fuel contamination and provide consistent readings even after years of sloshing around in your tank. The robust float arm won’t bend or break from the constant motion of field work.

Good to Know

Installation requires draining the tank and removing the old sender—a job that’s easier with the tank near empty anyway. Clean the mounting surface and use a new gasket if your kit includes one. This sender is specifically calibrated for Stewart Warner gauges, so make sure that’s what you have before ordering. If your gauge still acts up after installing the new sender, check your wiring connections at the tank and dash.
