I also ended up with a Holley blue pump after alot of trial and error on my 403. I had the pump mounted by the tank, and ran a line to a splitter in the engine compartment. From there, one line went to a regulator and then to the carb, while the other line went to an additional inline electric pump, and then to my NOS solenoid. The NOS inline pump was turned on when I made my NOS button active. I flipped a switch which gave power to the NOS pump and both solenoids, and made the button on my shifter handle "live". Pressing that button activated the solenoids. I never added a regulator to the NOS gasoline line, and never had any problems. Then again, that line only had added pressure when I flipped the "pre-juice" switch just prior to use. I don't know that the added inline pump was even necessary, but it was recommended by a friend, so I just installed it anyway. I never had any problems.
Even though the blue pump has a built in regulator, you should still add an external regulator in the engine compartment, IMHO. A gauge mounted to the fuel rail is a "must have" in my book too.
Take care,
