The fuel pump relay is built onto the circuit board and isn't serviceable separately. The fuse you're looking for is "M25". I added a red arrow to point it out.

Yes. The TIPM, (Totally Integrated Power Module), is the under-hood fuse box incorporated with a needlessly complicated computer module. Ford came up with this as their "FEM", (Front Electronic Module), one of two involved in blowing the horn. You know, ... What we used to do with a mechanical switch and a simple relay. Chrysler has been famous for coming up with all kinds of innovations that benefit car owners, then the other manufacturers copied them a few years later. Others have been very good at dreaming up innovations that benefit the manufacturers. Unfortunately, Chrysler copies those ideas too, and this is one of them.

I have a friend with a body shop who specializes in rebuilding smashed one and two-year-old Chrysler products, mostly trucks. He often replaces TIPMs that were damaged. Part of my background is in tv / vcr / car radio repair, and that often involved replacing or repairing relays. I've always wanted to get my hands on one of these to see if a relay contact repair will solve a problem, but as I said, they're always broken.

I was surprised to see they listed the fuel pump relay as being on the circuit board. Those relays are usually pretty small and used for relatively low-current circuits. A fuel pump motor can draw around ten amps. I wouldn't want to trust such a small relay to get me back home. Might I suggest you double-check your fuse box cover to see if they show a separate relay for the fuel pump. I'm going to look again at my drawings.
