Air Leak in Air Compressor Tank

I had a friend give me an old swan 60 gal 220v direct drive compressor with a bad tank. Scored a Husky 60 gal tank on craigslist, 2 years old and compressor blew a rod, for $100. Cut the mounting plate off the Swan and it slid perfectly over the Husky mount. A little plumbing and got a great high volume compressor.
