Cleaning dirty old mercury outboard motor fuel tank

I have an old fuel tank for an old Mercury outboard which has old gas in it. I want to clean it out the tank and make it useable again. My thoughts are to first drain the junk out of the tank, then flush it out with water. Keep flushing until all the junk is out. If it has any rust, then soak it in some apple cider vinegar and drain out again. If any rust still remaining, drop in some gravel and rock and roll.
Anybody do this before? Anything I am missing?

vinegar eats rust, fill the tank with it and let sit overnight, then flush tank out with soapy water, then let it dry.
its will completely eat the rust away to nothing.

Don't waste your money on Apple Cider Vinegar, the cheapest white vinegar you can find will suffice.

Ethanol might clean it some also. Not sure about rust though

And put a piece of chain in it and shake it.

This is exactly how Coleman aficionados clean the fuel tanks of lanterns. I’ve resurrected many Coleman lanterns that people have thrown away.
As others have said, just use white vinegar. Might want to slosh some denatured alcohol in the tank afterwards to prevent flash rust.

Dump it out. Plug the barbs where the fuel would come out. Fill with vinegar and a piece of chain. Leave it in the back your truck for a few days. Driving around will do the work for you. Take the proper steps from there to ensure it doesn’t flash rust. I’d do a coat of Evapo-Rust treatment last.

Chains make me a little nervous in gas tanks. Metal on metal can produce a spark. I have plenty of gravel around and I think gravel should get the job done.

It’s been done for years. You’ll have a blast getting gravel out of a tank. Bolts and nuts are often used as well.

Make sure it’s something metal that you can get out with a telescoping magnet.
