2001 Pathfinder Power Steering Leak?
 

I have a 2001 Pathfinder SE (3.5 v6). I have developed what I think is a power steering leak. The leak appears to be coming from a hard line on the drivers side front of the truck, from behind a retaining clip. I live in the midwest so I drive on snowy, salted roads, so it seems like I could have somehow gotten something behind the clip that either rusted or abraded a leak in this line.

My questions: does this sound like a power steering line? If so, which line is it (return line? pressure line?) and where can I purchase one most economically? If this does not sound like a power steering line, any clue what it is? The leaking fluid looks like PS fluid, and my truck keeps running low on it as well.

Thanks in advance.
