If you had a form that could help it keep its shape around the outsides, you could probably use compressed air to "inflate" it until it filled up the form. Might be a bit tricky, though. Another method could involve making an L-shaped bar that could be inserted through the filler neck and used to reach over to the dented area and pull it out almost like a gentle slide hammer. Just thinking out loud.

Ive heard of filling tank with water and popping it in the freezer to return to origional shape. Keep a sharp eye on it , however.

Compressed air is like a giant spring. Difficult to control. Fill it with water and hook your pressure washer to it. Should be able to pump the dent out. Better yet would some sort of hand pump.

Don't use compressed air. Anything goes wrong, you got a bomb. Always use a liquid- water. First, I would see how much I could pull out with a L shaped bar through filler.

I had a Huge Dent in the bottom of one of my 1969 Firebird gas tanks that I popped out by cutting a few holes in the top of the tank and poking cut off broom handles and other assorted 'tools' in through the holes to slowly hammer the dent out with, then soldered patches over the holes which were hidden under the trunk floor never to be seen again.

If you don't mind a couple patches on the bottom of your tank where most people would never notice, that would be another option for you. Might want to try an L-shaped hook stuck through the filler neck first though before going that route. Clamp it (the L-hook) hanging down under a vice, slip the tank over it and slowly work the dent out by tapping down around it like working a dent out of a fender with a hammer and dolly.

https://www.ottofrei.com/Snarling-Irons

Another unique tool, the snarling iron, is often used for raising designs on hollow pieces which have a small neck opening and the inside of the vessel can not be accessed with regular chasing tools. The snarling iron has a long arm bent at a 90 degree angle at the working end, which is slightly domed and polished.

This will work inside the tank with proper bends. O did a bad dent in a BSA Gold Star tank once and a 3" dent was just gone.......

I almost uncrimped the ends of a 10-20 IH gas tank with air, being very careful. Didn't remove the dent completely either. Different repairs for different dents I think, those snarling irons are interesting. Some I can get out close, then putty and paint.
