Used in-tank, fuel sending unit with the low fuel option. Tested and cleaned units for all 1967 Mercury Cougar XR7's and all Ford Mustangs with 16 gallon fuel tanks. This is an original 1967 fuel sending unit with three electrical prongs. Ford casting number C7ZF-9275-D. This unit comes with a new 5/16 inch filter, brass float, and sending unit gasket. The only difference between this sending unit and the 1968 sending unit is the diameter of the pickup tube. The 1968 verison of this sending unit has a 3/8 inch tube. These are completely interchangeable on all 1967-68 16 gallon fuel tanks.
*Note - Not compatible with Mercury Cougar Standard models (65A or 65C) or Ford Mustang unless they have the ultra rare low fuel warning light found with the convenience light option. The sending units without low fuel have 1 electrical prong.
**Low fuel warning portion will not be working on these used units, the Thermisters all failed years ago.
