Where is the fuel pump relay fuse located?

The fuel pump relay is located in the IPDM (intelligent power distribution module) and is not serviceable separately. The fuel pump relay fuse is number 48 - 15-amp in the under-hood fuse panel (IPDM).

Here is a guide to help test it:

BTW I have seen the IPDM go out causing no power to the fuel pump. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on. Here is how to change out the IPDM in case you need it.
