I can't help you with the tank-replacement information, but in the *meantime*, 
to lessen the continual re-fouling of your fuel system, you might want to 
consider doing what I did for an old car of mine (not an Audi). This car had a 
similar problem/challenge; different cause. After looking at what replacing 
the gas tank might cost in time and energy, I went to the local *big* auto 
parts store and looked over their rack of aftermarket-fuel filters. I found 
one that is translucent, sizeable, and in what I call a "drop 
configuration"...inlet and outlets at same level, with the filter hanging 
below, so as to catch crap and water. I installed this as close to the tank as 
possible, and check/dump it every couple months. Did the trick for me, at a 
cost of about $8, 25K miles ago. 

Don't know if this would work for you (mounting space? fuel line materials? 
too-high system pressure?), but worth looking into, for at least a cheap, 
temporary fix??
