Known issues on the 2021 F-750. This model year carries three recalls on federal record. On diesel trucks, a void in the underhood secondary fuel filter cap can grow into a pinhole and let fuel leak, and separately, biodiesel deposits can build on the high pressure fuel pump rollers until the pump fails and the truck loses drive power. On the gasoline version, the transmission oil cooler line can touch the air conditioning compressor pulley and drop fluid onto hot components. One owner complaint is logged with NHTSA, against the engine. Fuel system service and cooler line routing are the procedures involved.
