Re: Air Intake Manifold vacuum hose

Maybe double check to see if you can use a used intake manifold from another m113.
Here is one pretty cheap.

I would be curious to hear how it drives without the vacuum supplied or using an alternative source of vacuum as a temporary measure.

Yeah I have been looking around for sure, been finding a bunch of articles and posts from other who have experienced the same thing.

I'm speculating that Mercedes actually expected this hose to be replaced after the initial wore out by cutting it off and using a 4mm line, Part #56 in the drawings, why they didn't' do that from the get go with just a female part at the bottom of the intake for everyone and or typical male out on a 90 I'm not sure. But the link you have is doing just that except they are using a 4mm connector to make the connection, VS the hard line called out in the drawing.

I have some parts on order so with luck this wont be a issue. I will report back

This post https://www.benzworld.org/threads/answers-hesitation-stumble-wont-ac... can give you an idea of what the broken off line connection looks like and why the solutions in this posting and the early ones can work well.

If you buy a used manifold you should go ahead and install a more robust and permanent repair.
