Any of you had problems with a fuel pressure regulator making noise after it was installed? Mine makes a lot of vibration when it is cold outside.

I should also mention that I have the 5.3L and I installed the FPR to help with a hard start problem. That didn't cure the hard to start till I found a vacuum leak in the fitting that attaches the vacuum line to the regulator. Replacing that solved the hard start, but that's when the vibration started.

Did you ever get your FPR vibration problem fixed? My '00 Tahoe has the same problem.
