The previous two responses have been moved to A NEW THREAD in order to take the side discussion elsewhere. Jonathon Lottbrein, I do hope you keep responding.

 

So now I'm really kind of bummed out. I ran the check for pressure and bleed down at the filter and that was fine. Then I headed back up to the fuel rail to check the plenum again and that is checking out fine now. No more than 3 or 4 psi drop in 10 minutes after numerous checks. I really wish the results would have been repeatable and conclusive to say "THIS is the problem". I guess now I'm gonna have to wait til it gets bad enough to really give me a solid result.

 

What was max pressure at the filter? Did it come up to pressure immediately? How long did it take to drop and what did it drop to?
