My power steering hose has a slight leak where the two power steering hoses connect near where the fuel lines connect to the fuel rail on the passenger side of the engine. It is the threaded end of the hose seen here. I can't see it leaking but there is a small amount of power steering fluid on top of the valve cover and there was some on my finger after I felt the bottom side of the connection. The connection was already so tight that I was afraid I would break something if I tried to tighten it further. Is there an o-ring or something that helps seal this connection or am I just SOL and would have to replace one or both of the hoses?
