Man the search is so difficult on this sight. That random generator is REALLY bad. Tried to search for info on LLY FPR and after at least 15 tries without a single success. Finally just gave up. Even now I have to duplicate this gibberish to make this post. You would think after signing in you could bypass this PITA.

Not sure what is "FPR", or what it does. Maybe try FRP. If you have a specific question about it, this is the correct forum to ask.

The "gibberish" is only required for new (or not very active) users. It's a necessary evil to help keep the ne'er-do-wells at bay. You shouldn't be bothered with it any longer.

At any rate, Welcome Aboard!

FPR is fuel pressure relief. Then again it could be fuel pressure regulator, but there's another nifty acronym for that it's FCA.

To the OP. I have invested a great deal of time and effort in the subject area of the relief valve, shim mod, bottle test etc and have set up some nice Tech Tips:
