Hey, I have a 1986 MB 240D and I really want to update my vacuum lines and connectors.

I have a thread asking if anyone knows which model and year I should order from..since I have 1986 MB 240D.. (apparently many stores have 240D's ending in year 1985..and won't quote parts..and the 1986 300D just does not match most of my car)

Does anyone know what is the best model or order for my 1986 240D?

Does anyone know where to get a good vacuum diagram and then where is the best place to order vacuum parts..the ones that are not the simple 4 and 5 way connectors..or hoses. There are connectors at the top of the oil case, etc. that are not the typical vacuum parts.

Thanks!!
