Ok, to all the gurus out there, I have had a line failure on my 2002 Foz, just ahead of the right rear wheel, but just behind a small "box" that has both rear lines going through it. The fittings for the lines going into this "box" are shot - all the way around - as in there is no way in God's Green Earth they are going to come out of there - ever.

 

so the question is - just what the devil is this little "box"? (see attached pic)

Is it just a junction point (this is what I think it is, but?), or is it a proportioning valve?

 

if it is just a junction point, it can easily be eliminated from the system, yes?

 

FWIW - both of the rear lines at that point are in pretty bad shape, so seriously considering doing both lines and being done with it

 

correct.  just a junction box.  i just bypass them.  

 

proportioning valve i think is up in the engine bay. 

Thank you for the confirmation.
