Well, I replaced the fuel pulsation damper, and now I can watch the gas run out below it. It's a constant drip. It looks like it's coming out of a small plastic cap right underneath the intake manifold facing the front. What is this, and is there an easy way to get to it? I've got all kinds of **** in the way. Thanks.

The PD is the small plastic cap under the intake manifold? That's where it's running out. Hmmm, maybe I didn't. The guys at the dealership told me that it was also called the fuel pressure regulator. Did I get screwed?

Well, I got the cap off of it, and there was a screw just lying in the cap with a rubber O-ring on it. There was a hole in the center of the PD, so I screwed it back in there tight. Could that be the leak? I'd like to know before I put it all back together and start it back up again.

That is not fixed.
If you had fuel coming out of the hole, it means your diaphram has broken and is letting fuel get to that hole. The screw backing out and into the cap is only part of the problem.
If you didnt have any fuel leaking out then the diaphram is still in tact and you could have put some thread lock on the screw then put it back in..
but since you had fuel, when the damper moves the screw will slide out and fuel will still be able to leak out of the damper housing.

order a new pulsation damper, tell the parts department guys they don't know their heads from their asses.
