iTrader: (11)

Have a '04 lq4 installed along with a t56 magnum in my 69 Chevelle. Will run the truck intake/access, but will be using the Holley HP system to run the show. I have a stock sumped tank that has (2) 3/8 NPT fittings. Right now I'm running -6 feed and return teflon braided line along with a Walbro 255. My target HP is modest at only 650-700 FWHP. I was thinking of maybe "y-ing" in another 255 pump, but not sure if this will work with the -6 feed or should a -8 be run? How would I go about hooking everything up to the stock rails, which have a feed and return, the feed is larger of course. There appears to be some sort of vacuum pressure regulator attached, not sure if this can be retained or if I need a separate reg.

Nice thing about the Holley system is that it will only turn on the 2nd pump when needed (can be config to turn on for rpm, tps, map, etc).

Thanks guys.
