I found the the rubber elbow that plugs into part 65 mouted to IP was broken. I used a plastic fitting I found in my mityvac kit which was an elbow that sorta fit OK, just wondering what the little elbow did and what running motor with it broken would of caused. It has a small vacuum line that plugs into it. This is a 1987 300D turbo sedan. I wonder if this would cause the long cranking I was experiencing on cold start.
I will get replacement part from benz dealer but I dont know what to tell them it is / what it plugs into.
