4000 Q fuel problem - tank

[Tony Hoffman]

Well, I got into the noisy fuel pump problem today, and when I pulled the feed line off, it barely trickled out. Pulled it upstream of the pre-filter, ditto. Pulled the return line, and holy sh**, poured all 15 galons or so out. I filled the tank originally, thinking the problem was it was empty. Turns out the fuel gauge doesn't work. So, now I have 15 gallons of fuel in 5 gallon buckets, and one hell of a rusty tank. When I put the compressed air into the return, it blows right in. Do the same with the feed, and it blows back at me. It appears that Audi put a second "shelf" into there, so the gas wouldn't run away from the hole when cornering. Good idea, Foxes would cut out below 1/3 under hard cornering. 
 
The problem that it brings up is this, I can't get to the feed to clean it of the rust or whatever else is in there. 
Anyone out there delt with this before?
 
Anyone near me with a spare good tank for a 4000Q? I'm in Oklahoma City.
