Thank you Steve! That’s my issue, I finally can’t get them filled anymore and I’m down to half a tank left out of three.Welcome Anthony, nice looking Genesis 1000 you have there. I'm surprised you are able to still get those old tanks refilled anymore. All you have to do to get it to work with the newer tanks is either replace the hose and regulator or the quick connect fitting on your regulator with an acme nut. Don't hesitate to ask questions, you are in the right place for answers.
