Hose sizes?
 

This is going to be used on a EJ25 SOHC Phase II motor with MAP sensor. What i need to know are the hose sizes for these, and what kind of hoses that I need to get, since I'm replacing the stock hoses for higher quality pieces than stock.

Intake Breather
Vacuum
Fuel
Oil

What other lines are there that are worth replacing? Is there any other brand other than SAMCO that are worth using, since that's the only brand that I know of.

Thanks for any help.
