Gasoline smell around rear driver side tire.
On two occasions I’ve come to my car after it has been sitting and could smell gasoline near the rear driver side tire. I could also smell faint gasoline in the cabin after filling the tank one time but it went away quickly after. The fuel pumps were recently replaced and I thought they may be cracked or leaking but I had a mechanic as well as myself inspect them and there appears to be no leaking in the area. I thought maybe the charcoal filter but that would be on the passenger side. I am not really sure what would leak gas or gas vapor on the driver side wheel well though.

Pull up the rear seat bottom and see if the smell comes from this area. It’s likely related to the fuel pump repair work recently done. The in-tank components may not have been properly resealed.

So it looks like the fuel is actually coming out of the fuel line. I pulled it off cleaned it all down. I ordered the new line from MB should be in at RBM Alpharetta tomorrow anyone curious about the part number - A204-470-18-24

ok so the correct part for a C207/A207 is A204-470-14-24 it is about 6 inchs longer and $50 less than the one I originally mentioned. I did order a new Hella suction pump. 2184700994. I have a FlexFuel car so, you have to verify that it is flex fuel compatible.
Takeaways.
1. make sure your fuel tank is 1/4 tank or lower
2. use a rope or in my case a fish tape connected to the existing lines of suction pump, that you can then connect to the new ones to easily pull back through. I am sure you can fish them by hand but this just makes it easier.
3. don't cheap out and try to use a hammer and screwdriver/chisel to get the lock rings off... they won't budge. I bought this ( ) and with a breaker bar it was still a very hard pull to get them off/fully seated when putting them back.
4. thoroughly clean the areas around the pumps before removing the rings. I drop some dirt down in the tank, had to go in after it, even with doing what I though was an ok job of cleaning.

My dealership service advisor said that my charcoal canister is bad/wet with fuel and needs to be replaced. They said it is part # 212-470-02-59-64. However, they are saying the part cannot be found anywhere in the US, and Germany doesn't have it either (and they are not producing it). Do you know if there is a cross-reference or updated/compatible part number I can get?
I am desperate at this point, because it is throwing a CEL and the car sometimes stalls.
