Problem with Mighty Demon 750

Well now I've got a fuel pressure issue... I've got a Holley 125, brand new. It was pushing 6 lbs yesterday.. 2-3 today. I don't know what the hell is going on. I checked the pump filter screen. It's clean. I've got an Earl's inline filter after the pump as well. Not sure that thing could get plugged without the pump screen not having anything in it. And it's only got about 15 minutes of run time.
