Hi Everyone. I am leaking power steering fluid out of the connection where the high pressure line attaches to the power steering pump. Is there some sort of o-ring or seal that goes in there that may have gone bad? I've been dropping power steering fluid for a few days now, but was only able to identify the location of the leak today when I popped the hood at the gas station and the fluid was welled up on the connection. If there isn't an o-ring, maybe I just have to replace the line? If you are in the know, please let me know. Thanks!
