Ford has extended the warranty coverage of the fuel pump and sending unit assembly in 1990-1993 F150, F250, and F350 trucks. In some trucks, the check valve may become damaged inside the fuel pump unit. This can cause fuel to travel from one tank to the other, creating an overflow condition. In the presence of an ignition source, a fuel leak may result in a fire. Dealers will repair the fuel pump and sending unit for up to 12 years or 150,000 miles from the original warranty start date.

Ford has recalled certain 1990 E and F Series 4x2 vehicles equipped with an E4OD transmission and a one piece driveshaft due to an issue with the park mechanism in the transmission.

Dealers will replace the snap ring and install a revised extension housing

On certain vehicles, due to the routing of the return line, the hydroboost may stay engaged lightly, which may cause added brake wear and tear. Dealers will replace the return line and repair damaged brake components.
