I believe your fuel pressure is set too high. At 9lbs the pressure could blow by your fuel valve. I believe the Holley documentation for the 4150HP states the max pressure should be a max of 8 lbs. I run mine at 6 - 7 pounds and always get enough fuel.

Here is a link to the Holley tech info that may help: http://www.holley.com/HiOctn/TechServ/TechInfo/FMFPTech.html
