I would agree with others as the Holley black pump should be more then enough for your setup. I use the Holley black pump also and have the regulator press set at 6 psi. I use 3/8 line and a stock fuel tank with a stock 3/8 sending unit. It feeds my car fine as I have no fuel starve problems at all. I actually had the red pump on before and switched to the black just to be sure it was getting enough fuel but it ran the same 10.70's with the Holley red pump also. Ron
