A single line will work fine, but nothing wrong w/ going dual. The pan will be OK, as long as you have good oil drainback and don't flood the heads.
For a vacuum pump...Moroso, GZ, or Star make good pumps. Just DON'T use an Aerospace Components pump. Looks like you already have a Moroso pump.
ooook ! i have moroso pump and all hose but i dont know if fit with power steering , in my old 496 i used crankcase evac system for 10 years with good result .. but this can work on 572 ???
