I have a 1980 F600 with a 370 2V (N61HVJD9686). It sat for about a year and a half with a partial tank of fuel and condensation caused corrosion that destroyed the fuel sending unit and float. The original fuel tank and sending unit was replaced at some prior time with a diesel tank. The current sending unit has a drawing number of D3HF-9275-DA. Please locate me a sending unit and float. Thank you in advance.
