1984 Euro W126 500SEL, Charcoal canister and CAT removal

[werminghausen]

I am working on my Euro 500SEL which was first delivered in 1984 to Germany (around Stuttgart). I was imported to the US (don't know when), a grey market car (was converted according US specs I guess) and
I am trying to convert it back to its original state.

I'd need your help for the charcoal canister and CAT removal.

Charcoal Canister: I see a metal line ending at the left side engine ba. That line is connecting to the charcoal canister with a rubber line.
I removed the canister now and removed the rubber line but don't know what to to with the remaining metal line.
Does anyone know how the original tank vent ended?

Also I don't know where to smaller rubber line was connecting to. Could have been connected to a vacuum line..
As this smaller rubber line was loose I don't know where it was connected to. Does anyone know.
I guess I need to cap the smaller open line as well.


CAT, o2 sensor
Then I read that the grey market car received a CAT and o2 sensor, also a frequency valve?
I think I saw remnants, a CAT and butcher-installed o2 sensor.
Any ideas on how to properly remove all these parts and convert back to original?

Thanks, Martin
