Power Steering O-ring Question (leaking)

[Socom688]

My power steering is leaking where the hydroboost line goes into the pump (leaks from the part that swivels). To replace it, it looks like I just unscrew it from pump using a 11/16 bent/crowsfeet wrench, push back the unscrewed nut down the line to expose the male end of the line, and replace the o-ring, is this correct? Ive never done this before and I am fairly certain there is a Teflon o-ring that needs to be replaced, but what size is it? I've dug around but can't find an answer. Anyone know?

Anyone?

Thats it. Mine was leaking, I took the end off, cleaned it and the o-ring and put it back on. Hasn't leaked since.
