M1A1 Fuel Tank Sending Unit, 66-77 Ford Bronco SKU: 9660

WH Fuel Sending Unit | Reed Switch Style for M1A1 23-Gallon Tank

Get accurate fuel readings and a cleaner install with the WH Fuel Tank Sending Unit, designed for the WILD HORSES M1A1 23-gallon high-capacity fuel tank. Built with a factory-style wiring pigtail, this unit plugs directly into the stock Bronco wiring harness (and many other classic Fords) — no splicing required! If your Bronco doesn’t have factory connectors, no problem — the pigtail can be easily hardwired.

Measuring 11.25 inches from base to tip, this sending unit works seamlessly with your stock Bronco fuel level gauge, reading the same ohms range as the factory spec: 70 ohms empty / 10 ohms full. While built for the M1A1, it can also be installed in other aftermarket tanks that accommodate its length and standard bolt pattern.

Whether you’re restoring or upgrading, this sending unit delivers reliable fuel level readings and hassle-free installation for your classic Bronco.
