At least a -16 to feed the pump (I see some are now a -20). A -12 from the pump to the cooler/filter, and a -12 to the engine (all pressure hoses). Then assuming a five stage pump, there are three -12 scavenges off the pan and one -10 off the back of the block (lifter valley). At least one -16 return to the tank, but most are running two returns now.

And these are just general guidelines. I know there are a number of different configurations out there now, even with a second pressure line (-8) going to the front of the block. But this should at least get you close, or give you an idea of what you're looking at.
