my local hardware stores sell them.. while they can’t say it, and I shouldn’t.. they work on post 2009 cans too.
I bought a bunch of the EZPour replacement spouts for all my gas cans. It’s funny they don’t mention gas, gasoline or anything related to it on the packaging. They are made for “older style cans” is all they say on the packaging. They don’t how any “red” cans on the packaging either. Pretty funny.
