I'm starting to button up the truck and I am in the process of changing the oil filter. I know that there are after market filters with their own caps, so how do I tell? Inside the cap there is a number ">PA66-GF33<". I'm not showing it as a ford part number. So two questions. 1) Will this cap work with the ford filter as the filters look to be the same size 2) is the filter in there a Ford filter? If so I would guess that this cap is the appropriate one.
