I can't find the fpdm, I looked in the usual locations like by the fuel filter and back by the spare tire, cross members.
So I took some pictures on top of the fuel tank. I see something about a foot in back of the fuel pump which may be the fpdm? See attached pictures of left and right side.
I(f,,,you are looking for the fuel pump driver module,, you need to lower the spare tire and it is mounted on the chassis cross member. Get the replacement so you know what you are looking for. They are known for a corrosion problem where the back of the FPDM contacts the chassis and traps road dirt etc. The replacements have a better mounting that prevents it from trapping that trash..

I did lower the spare tire and looked all around and didn't find the fpdm. The only wires I found by the spare tire was to a small black box marked xf2x-9b328 m4d-911-a, see attached pic
