Description

This is the sending unit used in the 1968 Cougar XR-7.  It was also used in the 1968 Mustang and Cougar equipped with the Safety Convenience Panel option.  This option consisted of  four warning lights installed in the face of the center console if so equipped or in the center dash for non AC equipped cars.  The lights included a BELT reminder, DOOR Ajar, Parking BRAKE and Low FUEL warning.

This sender comes equipped with a new filter, brass float, tank seal ring, and thermistor.  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.  The thermistor is tested using all original Ford circuit parts.

This sender has two active terminal posts.  One provides the signal for fuel level and the other provides the signal for the low fuel warning.  The fuel level is measured by a variable resistor inside a triangle shaped metal housing.  The low fuel warning is provided by a thermistor housed in the brass bullet.

In some very early 1968 production (September of 1967) the fuel line was 5/16″ diameter, and the fuel sender main tube is also 5/16″.  We don’t know for sure but those cars may have been equipped that way during the strike period in late ’67.  If you have one of those you should use the ’67 sender.  The fuel line size was increased to 3/8″ for all later production.  The tank held 16 gallons.  This is the correct 3/8″ sender marked with the Ford part number C8ZF-9275-B.
