Champion fuel rails for stock intake

what configuration?
stock lines and stock regulator on driverside ,
single AN feed (-8 or -10) with stock regulator on driverside
or dual feed external reg and what size AN fittings

for what its worth i was on stock lines and rail down to 10.0 with doublepump walbro340Ms (and meth dual nozzle)
and only upgraded to a -8 feed and 6 return and still using stock rail

Just swapped from stock lines to racetronix, and, my dual Reds pumps to racetronix as well. Just want to be safe as I can be with a new (ta) block.
