get the 4 port regulator...and you can do it several ways...#1 use the extra two ports for Nos..since its an already regualted port..DO NOT REGUALTE AGAIN...anything you plumb off the free flow port must be regulated again..
i would just block the extra two ports and go with the NOS selenoid fuel log and plumb from the free flow port...
