I just replaced my HPOP because of a leak on that plug a couple weeks ago. Thread is here:
help 99 7.3 stalling while driving
I started to pull the plug, but it was cold as hell that day (like 10-20) and I didn't have a garage to work in, so I took the quick route and just replaced the HPOP. You have to torch it to get that plug out, and few places sell the full oring kit.

This is one of the few places that sells a full 7-piece HPOP oring kit, and they have some instructions for plug removal.
