As a side note, the glue you pour into the tank will work most of the time. I had a bad reaction one time, or maybe some old sealant but it stayed for a month or so then started comming off in sheets. Had to remove the tank, cut it in half, scrape out the sealant and then while apart cleaned out the rust. Welded the whole thing back together filled it up, found a leak. And then replaced the tank. Live and learn.

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
