Hi All,

I have one remaining tube hanging loose in my 1990 760 Turbo. I have included a picture. It is very thin and yellow. It doesn't look like the vacuum or fuel lines elsewhere. There is another tube that looks like it that is connected. Both come out of the firewall on the passenger side. Does anyone have any idea what kind of tube this is and where it might terminate? I have a feeling it might need to connect to a different size hose before it terminates, since the other one does, but I don't have any idea where it might go because I don't see any more openings anywhere.

Thanks!
Rosa
