2G air leaking out of fuel rail end.

I recently did the pcv delete egr block, and put new o rings and new fuel rail. I smelled a little gas but figured it was the little bit that spilled just airing out. Well this morning i smelled it again so i pulled over to inspect it. Where the stock fpr connects to the fuel rail i hear a tiny psssss. Coming out. I have the fpr tightened really good but still leaks and smells of gas. What are my options to fix this? I don't think i should wrench it any more because bolts break so easy or strip the fuel rail like i have done before. Is there a gasket of some sort for this? I won't be home for a couple of hours but am going to take it apart and check the o ring that is on it when i get home. Thanks for all advice.

If its hissing from the fpr, it is more than likely the o-ring on the fpr not sealing properly. tightening it more wont help your problem. Pull off the fpr and inspect the o-ring, it will be in the groove on the end of the fpr body. the fuel pressure regulator should fit pretty snug, replace if needed and see if it stops hissing.

That is exactly what i checked this afternoon. O ring was not in the best of shape. Replaced it and leak is gone. Easy as pie. Thanks for the info though. RESOLVED!

You did use an oring suitable for gasoline right? An oring is not just an oring. Material is important. Gas, hvac, oil, etc. An oring suitable for a harsher environment can be used elsewhere but not vice versa.
