  • This sending unit does NOT come with the "funnel filter." If your old filter is no longer useable, you will need to purchase a replacement filter.
  • This unit will NOT work properly in the 1987 or newer Ford Full-Size pickups with the a diesel engine. In 1987, Ford flipped and extended the Ohm range so this sending unit will read full when empty and empty when full in a 1987 or newer Ford pickup.
