Fuel pressure regulator question

[Maiello169]

I was looking in my engine compartment and for whatever reason I popped the cover off the top of the regulator to find the adjustment screw just sitting on top, this is on my factory regulator , any idea how this would happen ? Could this cause issues like this ? Should it be fully tight ? Any help would be great , thnx

that screw wasnt screwed in and not sure if that could be causing any issues? The scre was completely backed out laying on top of it , any ideas ? Should it be completely tight or adjusted a certain way ?

no idea wtf that thing is but thats not the FPR or at least not what the parts store call the FPR. lol

It's the FPR diaphragm or something, that is very common I see it all the time my car was the same way. Just screw it back in not too tight but snug so it won't back out again.

that "screw" you are talking about is on the Fuel Vibration Dampener as got adjustments... im lost myself =/

So I should keep it tight on there but not to tight , sounds good too me lol thanks a lot
