Guys, the thing is that I wanna get rid of the rust. Sure what Denny is saying is a great idea and several people have told me the same thing roughly. But the thing is. Just getting big pieces of rust isn't going to solve my problem. For that matter the problem isn't pieces of rust. The filter so far hasn't had anything solid in it. It's just powdery rust and gunk.... no solids. If the rust was bad enough that I was getting whole broken chunks out by rattleing stuff in it, then I would think the obvious approach would be to get a new tank but we're talking about an '85 Monte Carlo. It probably just has light surface rust that is mixing with the gasoline.

What I wanna do is chemically treat the tank without having to order somebody's super duper $50 rust removal kit. I am sure there are chemicals I can buy from the store to "treat" the rust so that it discontinues to rust. I found some stuff at Lowe's that supposedly is used on metal to "treat" rust before applying primer and/or paint. However I am not sure how it would stand without being covered by something and I don't know if it would have some adverse effect on the gasoline or the engine.

Tomorrow I am dropping the thing and seeing what the whole picture actually looks like. Thanks for all of the comments. As always your diverse minds are helping me to conglomerate a devious attack plan of my own.
