Power steering question

[LEMHEAD16]

When I started my project I cut the ends of my power steering lines so I could figure out what size they were, my problem is I didn't mark which one was the pressure line and which was the return, I am stumped.

Which port (on the rack) is the pressure side? The small port or the larger port?

smaller bolt is the pressure, and the bigger on is the return to the reservoir
