**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. Please look at our entire line of Ford Diesel Sending Units to match your year and tank position.
