The Motorcraft FD-4627 is the fuel filter service kit for a 2018–2021 F-150 3.0 Powerstroke. It is both filters. The frame-mounted filter and the underhood filter are in the box.

These are the factory elements, so the micron rating stays where Ford set it. A plugged filter is a hard start, a stumble, and a pump that has to work harder. Change both at the same interval. The housing and the water separator are not included.

It fits 2018–2021 F-150 trucks with the 3.0 Powerstroke.

Drain the water separator when the filters come off. Water left in the bowl goes right back into the new element.
