V10 fuel pressure?

V10 fuel pressure?
Any body changed a fuel pressure regulator on one of these? I'm having an issue with it running really lean, like laying down with no power lean.I put the pressure gauge on it and I'm running an even 30 pounds at the rail. Changed the filter in hopes, but no change.
Just changed the O2 sensors and they were both white.

Guess I should have taken a test drive before posting. Changing the O2 sensors straightened the problem out. Go figure, I knew that they could go bad and not throw codes, but had never had one fail on me like this before.
Out of curiousity I ran it with the fuel pressure gauge hooked up, It stuck constant on thirty, I even tried pressing the pressure relief vavle on the side of the gauge and it didn't even stumble, pressure dropped to 20 and then bounced right back up to 30.
Now if I can trace down my itermittent miss I'll be set. I have the feeling that the plugs are original, judging from everthing else I've fixed so far.
