We've always done a -10 to regulator, -8 to a fuel log on the carb. Haven't had any issues yet, done this on multiple cars/multiple motors and different pumps. If you are not running a log, then two -6 lines to each bowl should be sufficient as well.

When you consider the id of a -6 hose compared to the needle/seat opening it's the orifice of the regulator that would more likely be the restriction than the hose.
