I think the California Air Resources Board (CARB) is the source of the Regis that brought about the vaporless nozzles and gas cans.
Me.. I just use water jug nozzles that I get off eBay. They even come with vent plugs.
I can’t find one that fits Briggs and Stratton cans. And it adds more money to fix them.
I hope you paint them red.
