Tank cleaning, Or new? Options

[r_towle]

What is the new “best practice” for removing and cleaning a fuel tank?
Car sat for 15 years.
Previously I took a tank to a radiator shop to have him boil it out.
He decided that drilling a 2.5 inch hole on top of the tank, drivers side somehow made sense. He did repair the hole as just normal practice. It looked like shit, I tossed it out.

Just needs fuel system redo and seals.

I also heard someone is making new tanks now?

We just went through this, but the tank was empty, West coast car had been sitting for a while. Tank looked original never been removed prior to our removal. I plugged the feed and return lines and added a couple gallons of new gas. Swished it around and around and emptied the gas into a clean 5 gallon bucket. I let the heavy stuff settle and poured clean gas off the top. What was left was a very fine dark brown residue, probably not rust. I repeated this several times until I was getting very little residue. Tank is now installed and seems fine. I also flushed the fuel lines and changed the fuel filter a few times.
