It would be number 4 idk what that part you sent goes to or where it would be I never seen it before

 

Can you help me find number 4 and educate me on that part you just sent me

 

I don’t know much about that part. I just searched eBay for air intake hose for a 1986 300e. Where did you get your part diagram? Does it have a text description for it?
Where have you searched for the hose?
Have you tried calling Mercedes Classic Center?

 

I have called them and I’ve tried ordering online apparently the air cleaner hose is discontinued

 

Were you ever able to find that part #4 - "hose"? The part number is 103-090-03-82
It is listed as discontinued but searching by part number may be helpful.

 

Contact the MB Classic Center via phone or email listed at their site (below) and ask them about that part number specifically.
