i don't know, but it seems to me that fuel systems get way overthought and over bought.

i run the stock 3/8" fuel line and pickup to a carter mechanical pump from mancini. from there i run 5/16" line to a tee, and 5/16" line to both carbs. essentially, it is a stock hemi system.

the pump was supposed to self regulate to the 5.5-6psi that the carters need, but was all over the map, as high as 10psi. i got another pump from them, the same. so i hung a holley regulator directly off of the pump. other than that, this is a stock system.

so far i have no indication of starving for fuel, and i run 2 650 edelbrocks. granted, i haven't taken it down the track, so i don't know what it will do after 10-11 seconds of full throttle, but if there was an issue i could most likely up the pressure at the regulator and that may solve it, even for the track.

so a basically stock system is feeding 540" and 1300cfm, so far with no issues. and yes, i do pound it!
