Re: Screw on the end of the Fuel Rail (sinolimitssi)
Pulse dampener...
I can't remember exactly what it does but I know when I changed my head gasket I had to replace the crush washers because it was spraying gas all over the place...
I think it quiets the pulses from the injectors and helps maintain a steady even fuel supply. I could be wrong though.

Re: Screw on the end of the Fuel Rail (EJ1 wilcox)
Hmm.. Well that screw was adjusted in and out and my car seems to be running like crap. They told me that was how you adjust my fuel pressure regulator.??? All i know is the guy adjusted it in and out and my fuel pressure guage didnt move and my car barely excelerates now. I have a hard time keeping up with traffic even. And now also when i try and excelerate hard i hear a fast repetitive snapping sound under the hood. Just trying to get some ideas what the hell happened.

Right on the money.
That screw was set from the factory and I've never seen a procedure for resetting it. I've never even seen someone try and mess with it in hopes of adjusting fuel pressure - so this thread is a first.
Was your car running like crap before that screw was ever messed with? The fuel pressure regulator on Honda/Acura's are non-adjustable.

Re: Screw on the end of the Fuel Rail (EE_Chris)
Yeah the car was running crappy before this screw was adjusted. But i found out the problem it was running crappy was because one of the fuel injectors plugs were loose and only running on 3 cylinders. I have a b20 in my car so i had a fuel regulator put in and a fuel pressure guage also. The guy at the shop thought maybe the car was running to rich with the fuel psi up to high, and quote un quote adjusted that screw saying that it is like that on american cars why not a honda. i dont know. Its running shitty now.

Re: Screw on the end of the Fuel Rail (sinolimitssi)
You had an adjustable FPR, along with an FPR gauge installed, but the guy who installed it didn't know how to adjust it??
Well, either way - what is your fuel pressure sitting at right now? What adjustable FPR did you end up getting?

That dude is a complete moron
DO yourself a favor and dont let him near your car again...........
Anyway, I would adjust the fuel pressure via the FPR and set it to stock and see how it goes from there. If the dampner is the problem, then just go to a junkyard and pick one up.

Re: Screw on the end of the Fuel Rail (extra cam needed)
i dont now what fuel pressure regulator i have. I beleive its sitting at 55 ish. And as far as i know stock is 43 and its supposed to be 60-65psi with the b20. I have no clue how to tune that. And the guy that installed the fpr wasnt the one that turned that screw. It was some other guy that is a local mechanic. uggghh I need help. lol

Re: (IslandSi)
