Dub, since they are so inexpensive I was planning on replacing the filter and pressure regulator anyway, but I didn't think that you (the royal you) needed to change fuel filters that often on newer cars. Guess I'll give Merlin a call and get everything out here for the swap. Although, since my symptoms are the opposite of your description for a faulty FPR, maybe I don't need a new one.

Thanks for the input, as always, y'all.
