I replaced the FPR today using Dino's awesome instructions. I cut the allen wrench too short, but used a stub with a 1/4" wrench and a deep-well socket as a pry bar. When I got the old FPR out, I noticed it's screen had some residue in it. Also noticed the FPR vacuum hose was cracked at the FPR and at the manifold connection. Bought the FPR from Advance Auto Parts for $41.99 and it included a new snap-ring, which I am glad since I hate reusing snap-rings.
