Sorry, my turn to not be on for a bit. If you can still get some photos I would appreciate them. Did the tank come out of a 5000 avant? I don't know what other models would fit and any information would be great. Thanks again for taking the time.

Is your car a quattro? If so, any quattro type 44 tank will do. You might have to change the fuel pump retainer from your old tank to the new, but they'll interchange too.
