I had an article that described how to diagnose fuel pressure problems, but I seem to have lost it... this is my problem.

I took the schrader valve fitting off the fuel rail today to see what size fitting I need to make my own line for my fuel pressure gauge. The car had only been off for about an hour and a half. I should have still had SOME pressure in there and expected at least a little spray, but the fuel just dribbled out. The article talked about pinching off lines & such to determine whether it's leaking injectors, bad FP regulator, or whatever. Anyone have any idea where I can find it or point me in the right direction?? I have a feeling this is why my car is running so rich and why I'm only getting about 12mpg. Thanks in advance!!

I think you might have seen the info from Street and Performance? I remember seeing this discussion on a video of theirs. I remeber the talk about pinching a line to blow the injectors out maybe on the return line?
