Hi guys, new here. I'm 38 yrs old and coming from Croatia. Few months ago I bought '03 RS6 avant in very good shape, really love it. It is my second Audi, first was S6 2.2T back in days.

Have some issues now, my fuel tank leaks at some sort of valve on the top of it. Driver side. Have read that was common problem, and that was maintened by Audi free of charge, at least in USA. My Audi delaer here in Croatia won't cover it, and new fuel tanks is out of option because it is really expensive
So I took it in my local mechanic, we took the fuel tank down, (what a PIA :/ ) and we found the place where it leaks. Plastic is broken where screwdriver pointing at.
PLease can you tell me what epoxy or some other similar thing to use to fix the leak? Maybe some other method?
Thanks in advance
