126 help?
 

I am trying to figure out where this vacuum line should be going? Anyone? Trying to help my team...

Can you back up and take a little broader shot? Put in an arrow to show the line in question? I cannot make anything out of the pic.

FYI
 

That is the warm-up regulator atmospheric vent.

What is the year, make model and VIN# ???






.

1985 380 se. wdbca32c4fa171158

It also failed it's emissions test, NOx, scored 3391 ppm, where allowable limit is 1758 ppm.

That is just a vent line for the WUR on my 500SEL
