4x4x2 power steering lines.

So I got a 4x4x2 box from a forum member and a Saginaw pump and new lines from west coast broncos. My question is my pump came with 2 different size o-rings. Do I need to put these on the high pressure line from west coast broncos or is the line set to be put right on?

I think it goes here. But when I got the pump it already had that part installed. I wonder why they sent an extra with it. Guess ill be pulling it apart to make sure
