So things have escalated quickly. I used the POR degreaser and then I used Rust911 to work on the rust. After three days I drained it. It kept clogging, so I had to blow the line to clear. The Rust911 said you can keep reusing until it turns black. Well it came out black. Removed the tank from the car, noted a large amount of debris in the tank, using long screwdrivers, wood sticks and a bent flat bar to break up all the stuff between the baffles, tank looked pretty decent, I couldn't see much with my inspection camera behind the baffles. Next I tried lead shot and mineral spirits with lots of lifting, shaking and rotating. That's when the black tar chunks stated appearing again. Hosed out the tank again into three 5 gallon buckets,. And kept coming out dark. Inspection camera revealed a layer of black tar sediment behind the baffles. Going to try laquer thinner and soak it for a week to see if I can get it to dissolve.
