2008-2014 STi OEM Fuel Filter Replacement - Updated with Pictures - NOT "SOCK" FILTER
Updating this post again now that I finally got around to replacing my OEM Fuel Filter today. I hope this thread sheds some light for anybody that has recently hit 60k miles and is looking to replace their Fuel Filter. (Recommended replacement interval is 60k).
There are a lot of people on here and nasioc that think the OEM filter is just that "sock filter" that needs replacing, and so they recommend replacing the pump with aftermarket. That "sock" filter is NOT the one serviced in the FSM.
Here is what the filter looks like:

And here is the filter attached to the fuel pump. You can also see the "sock" filter in the background.

And here's a picture of the filter media in case y'all didn't believe me :lol:

Here are the parts required for anyone looking to replace their OEM Fuel Filter at 60k like the FSM recommends. You are welcome to change to an aftermarket pump at this point since you have to separate it anyway.
Fuel Filter: 42072AG140
Springs (Quantity 2): 42047AG000
Cushion (Quantity 3): 42043AG240
Gasket/O-Ring (Quantity 3): 42025AG070
Gasket/O-Ring (Quantity 1): 42025AG080
Clip: 42032AG000
Spacer: 42046AG020
Also there's a great write-up on nasioc here:

Hope that clears everything up
