Bermblaster,
Have you checked to make sure the pressure guage is good. I was pulling my hair out with mine. Check this, change that, adjust the regulator everytime you look at it. It was the expensive f##cking liquid filled pressure gauge that was no good. It was brand new. Took it back and put a cheapo on, and it has been good since. If you have the Holley regulator with one in and two out, you should have both the outlets hooked to the carb like in my picture. I am also running the Holley black pump with the huge MrGasket filter you can also see in the picture.
