Oil feed line back to sump

Hey guys,
With a turbo setup for the oil feed from the turbo back into the sump - is it pressurised or non-pressurised?
What do I need to be looking for with the return line? Just any standard hose or should i be using AN6 fittings?
Would a rubber hose suffice for a short while?
Any help would be awesome! Thanks guys
