2004 A4 1.8T fuel leak from vent line

[chuddly71]

I was wondering if anyone else has had the same problem with their A4? I have a fuel leak come from the vent line from the bottom of the charcoal filter. It isn't a constant leak and will pulse out every so often. Hopefully someone else may have seen this issue before or may have suggestions of what I may check to see where the problem is.

Any help would be greatly appreciated
