1987-1989 Ford FS PU 19 gal. REAR tank Diesel SUSKU: TREXFMSU-5DER
1987-1989 Ford Full-Size Pickup 19 gallon DIESEL ONLY (REAR OEM style metal tank**) sending unit. Includes a new lock ring and O-ring. Purchasing a new “funnel” style in-tank fuel filter (TREXFMFF-1) is recommended when installing the new unit.
*The REAR OEM style metal tank is approx.. 25 ½” x 33 ½” x 7 ½” in size. If your original tank is an OEM Plastic tank, it is narrower between the frame rails and almost twice as tall as the OEM style steel tank so this sending unit will NOT work. Look at our TREXFMSU-12DEP unit if you have the OEM Plastic tank with a plastic nut that secures the unit to the tank.
**This unit will NOT work properly in the 1985-1986 Ford Diesel Pickup. Ford flipped the Ohm range in 1987 so do not purchase for either of those years. Look at our TREXFMSU-6DER unit.
