Fuel Volume Problem

[lvrpool32]

I am running 4 Dellorto's (48MM) on my 396 small block and I seem to have an issue with fuel starvation. Not with the jetting, my AF is spot on, what happens is if I drive it around and get on it a little it acts like it has run out of fuel....i leave it sit and crank it, 30 seonds later is starts and runs great. So I am guessing I'm draining the fuel bowl.
I have 6AN lines from the tank, to a FRAM fuel filter, to the holley pump (blue) - 6AN line to a regulator then a fine filter, then feeding the carbs in series (i.e. one line going to #1 , then to #2 then to # 3 then ends at #4.)
I have a feeling that I am confusing the low pressure requirements of these carbs (3 psi max) with the need for volume, basically I am not feeding enoguh fuel in to keep up with demand.
So my plan is to run a 8AN line from the filter, to the pump to the regulator, but then I have questions....
1) would it be better to run two regulators - use a fuel log and have two regulators mounted and then feed the 6AN line to just a pair of carbs.
2) would it be better to run 1 regulator, but run an 8AN into it and then an 8AN out of it to a Y then 6 AN from there.
Are banjo fittings bad for flow??? as bascially each carb has one, was wondering if I would be better of running individual lines to each carb with a 90 degree hose end.

Thoughts?
