Interesting! Didn't know they changed the fuel filter setup on the 2021 models.
Search of parts.ford.com shows new kit number is
FD4629 but interestingly the kit only contains the small metal one up front. According to the parts diagram, the filter location has moved from the firewall to up front on the engine in between the heads and comes with a mounting bracket:

Not sure what the part number for the large one near the tank in for the 2021 models.
Wonder why they changed the design? New location looks to be where the oil filter is on the 2018-2020 models.
@Paul Neubauer - can you post a digital pic of your engine bay? Things look a lot different in the 2021 models.
Looks like CarID has the newer FD4629 style (small one) in stock:
