Greetings,
I am currently getting ready to replace the vacuum hoses, and connectors for my 93 300D. It seems that 3m.m i.d is the standard black rubber hose "sold/recommended" for this vehicle.
My car on the other hand has 3m.m and 5-5.5m.m running around. It seems that at some point someone made a mess of things.
My main question:
Does the system require(from factory) 3m.m i.d rubber hose all the way around with step up connectors at the respected junctions? (Like step up to 5@Egr...
Vacuum system... Hose I.D reality, connections etc
