Well no o-ring there. I tried to use teflon tape as that is how it looked when I took it apart. But it still leaked.
I have identified which line it is. It is the line from the hydro boost to the steering gear. Problem is no one carries this in stock. They carry the one from the pump to the hydro boost.
So now tomorrow I will see if the local parts store that makes hydraulic hoses can make me one for this application.
