if it ain't broke don't fix it, but the fuel pressure regulator is 13 years old and more than half of that was storage for the winter, which is apparently what shortens their service life. i heard a loud pop from the FPR when i first turned it on this year, 8 months sitting will do that, but it started an ran ok.
i bought a FPR anyway and when i changed it out today i though of my opening line while fuel puked all over the floor.
none the less-best $60 tuneup i ever did, it had a rough idle and i was starting to smell fuel and i thought maybe i need a different map. now purrs like kitten running nice and lean feels like brand new.
if yours is old, you'll feel a difference its easy to change out except for the fuel mess, maybe there's a way to avoid that too.
