For fun, I just ambled out the garage (I work out of my basement some days) and gave the old FPR a tug to see if I could check the Oring.
The FPR is accessible but it is in there but good. Reasonably hard pull by hand doesn't dislodge it. The guy in that thread you reference had his FPR blowing off at 10psi, which would certainly create a sucky situation as seen with me. :| Ah well, a 200 Dollar stupid filter housing is less than a new bike, and I can keep my beloved Strom. (my wife observes when I threaten to shitcan it: "You are pissed because it is broken and you love it, not because you actually hate the bike." She's smart.)
