Default 8-71 Roots LS1 fuel sump outlet size?Fuel line size? Style/size fittings from sump?

In the works of putting a dual carb'd 8-71 Weiand blower atop my 5.7 LS1. To begin i ordered a fuel sump from summit with 1/2 npt outlets rather than the 3/8 npt outlets. Does anyone which is the right size outlet? What size fuel line and fittings coming from the tank would be necessary?

1/2" = -8....So I would go at least -8 to the pump and up to the regulator/s where you could then go either -8 or -6 to the carb/s.

Also, is this going to be a deadheaded or return system ?
