Removed my fuel cap last night to fuel up and got a woosh of air, assume it was going into the tank due to a vacuum. That said, I need to clean or replace the fuel vent. Does anyone have a diagram of the fuel system on the W115 300D they can share or, point me in the right direction to find the vent line?

I googled the subject and found only diagrams of the gasser versions.

Thanks in advance,
Curt

Here is a picture of the vent removed from the 1975 300D I used to own.
I believe it was located inside the passenger side of the trunk. I had a dirt-dauber clog up one of the small hoses. Hope this helps.

Perfect! Thanks rog-o. I thought that was what that was but wasn't sure.
