Hello all, 
  
I have a 2001 Pathfinder LE (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.
