Get your low fuel sender rebuilt to function like new!

After 50 years your old sender usually reads lower than the actual fuel level in the tank or maybe nothing at all.  We can restore it to work like new.  In fact our hand calibration process will actually make it better than new.

This sending unit was used in the standard hardtop Cougar and Mustang from 1967 to 1973. (This is not the sender used in the Cougar XR-7 or Eliminator, or the 1967 and 1968 Mustang and Cougar equipped with the low fuel light.)

This sender comes equipped with a new filter, brass float, and tank seal ring.  Each sender is hand calibrated to factory specifications and individually tested in the original factory circuit including an original Ford Instrument Voltage Regulator and Fuel Gauge.

This type sender has one active terminal post. In 1971 they added a second alignment post.  The active post provides the signal for fuel level, and the sender is grounded through the tank.  The fuel level is measured by a variable resistor inside a triangle shaped metal housing.
