Just like the title asks ... I broke the line and need to find a replacement

 

Are you referring to the line with the braided cover that goes to the hex head that the wrench head is next to? (BTW The red ellipse on your picture is not placed over any one thing.)

If so, that is the EGR hose/line and it goes to the exhaust manifold. The EGR valve is the black cylindrical thing above your the two fingertip above the wrench in your picture.

 

I deleted the EGR today until i CAN get a new line .. I also found out where my coolant leak was coming from .. Kinda bummed that I just spent 6 hours changing the intake manifold gasket for no reason but on the plus side I don't have to worry about that for a while
