So I Have a nice little puddle from time to time below my power steering pump. I have norrowed it down to where one of the lines that goes into it. Seems like the seal is leaking? Do they have a rubber o ring on them to seal the line to the housing? The line pivots and such but the fitting is very tight. I just wanted to make sure I should only need an o ring or that there is in fact an o ring there so I don't tear into it and f something up no knowing.
