1992 190e 2.6 vacuum line help
I have a 1992 W201 2.6, and I have vacuum line fittings that I have no clue as to where they all go. 4 of them to be correct. 1 goes to EGR, 1 to smog pump where do the others go to? They are on the left side of engine on firewall. If you can find the time to tell me where they should go, and their purpose, i would greatly appreciate your help.

Ok so here are some pictures for you:
A) is the smog pump connecting to the air diverter under the EGR B) is the small tube that goes from the air diverter to the port under the check air valve. In your 3rd picture there is that Y- splitter and I see that you don't have a vac line connected to the one on the bottom right, that is where the vac to the air diverter connects. C) is the vac line from the EGR to the bottom left port. D) is the vac line coming from the Y splitter (check air valve) that runs across the top of the crankcase underneathe the air filter housing and connects to the ...not sure what the name is, but it looks like you have that already connected.

Never seen that vacum pipe going through the ht wire cover on any other m103 engine .Loks like a make shift job to me .Would be better going along the rear of the bulk head .
