Many of the things were mentioned but there are quite a bit more listed there.

Thanks, lupuseven. Hadn't checked there! 
I connected a gauge to the front of the fuel filter housing, (the plug with 6mm allen wrench) and just wondering, is that after the filter and regulator, or before. I imagine if I would have looked at all I'd know... The pressure was 58 psi, with a drop to about 55, 56 under load so it's getting fuel there!
Thanks for all your help and advice so far, friends! Appreciate it!

Hello there again.
I had decided to check the high pressure oil system for leaks on my 2003 6.0 and I heard a gut growl way down there somewhere. I kept tearing it further apart, and finally discovered that air is allowed through the high pressure pump. If I'm not mistaken, that shouldn't be allowed. Am I right?
Now, if that is correct I imagine I'll need a new pump. Any recommendations to improve fuel economy?

NO air should be passing through the high pressure pump into the low pressure side.
Hope this is a clear explaination.

Very clear indeed. I'm only a step ahead, as I have removed the oil cooler as well. Bubbling right from the pump intake. Thanks crewdually.
Any advice for replacement? Stock or Performance?

I replaced mine with an updated Ford, but I have an 05. I've seen a few of your style (03-04.5) grenade and it seems alot of guys go with a performance unit then it's done. Maybe some 03-04 guys will chime in.
