I run:

Plastic cell with GM fuel sending unit
Dual -8's out of the cell to dual Walbro inline 255's
Then both lines come together with a NOS -8 Yconnector
It splits again just before the rails -8 to each rail
I'm running aftermarket rails from Edelbrock and both ends are threaded
Each rail has a fitting on the front side that T's off.
One side of the T from each rail is a -4 going to an Aeromotive regulator
The other side of the T feeds a N20 noid
From the regulator it's -6 return to the cell.
