Thanks for the replies and the helpful advice. Here's what I've done. I continued to blow air, from my compressor, into all the openings and from different angles. I also had the shop vac nozzle stuck in the filler neck as I was blowing air in. I continued this until there was no more, or very little, brown dust blowing out. Then I put a short piece of chain into the tank and swished it around, concentrating on scraping the top clean by turning the tank upside down as I swished it around. Then I went back to blowing air in again. Then I mixed up a strong solution of a Melaleuca product called "Tub & Tile". It's a citrus based cleaner that cleans rust stains from sinks and tubs. At full undiluted strength you can soak a dirty old penny in this stuff for a while and it will come out looking shiny like new, so I figured it should work to clean up what ever rust dust was left in the tank. After flushing it out several times, it now looks really good. It isn't bare metal, but it's a gray color, similar to the picture in the above posting. I can see the pickup tube and it also is gray with no rust. I may have gotten very lucky here. I've decided to go ahead and use the tank as is, and add an inline filter. At least until new replacements are once again available from Kanter. Thanks again guys for the replies. Nice talking with you Howard, take care. I'll post again with an update after I get back from the Good Guys car show in Des Moines Iowa at the end of the month. That's going to be about an 800 mile round trip.

Anyone have advice on what I can do to clean out my gas tank? While replacing the sending unit, I noticed a fair amount of what looked like surface rust. I emptied all the fuel out, shook the tank and all kinds of small loose rust came out. Now when blowing air into the tank, I just get a cloud of brown dust coming out, but no more chunks. I've flushed it with water once already. What more can I do to get the rest of the powder/dust out. Up till now, I've been driving the car with no problems, even with all that loose rust in the bottom of the tank. Do you think I'd be alright as is ... or? I've read on this and other forums, about all the tank cleaning, prepping and coating systems, and the vinegar or other acid methods of cleaning. I'm very leery about applying some sort of coating since there is really no way of being sure that the surfaces are perfectly clean. I don't want to have the coating come loose and plug things up. Kanter offers new tanks for my car, but they are on back order, and won't be available till maybe July. Any advice will be appreciated - Thanks
