Its a Federalrequirement effective 4/1/02. Its not so much the shape of the spigot, but that it shows the propane bottle has an over-fill protection device. Such a device prevents te tank from filling more than 80% to allow for expasion of gases. Its a safety issue. Not related to California at all
I appreciate the response. They did say it was a safety issue but I was not aware of any gigantic problems in this area. Sounds kind of like the "gas tank filling" must pass along warning of last week.
It still would not suprise me if this is some brilliant idea to get us all to replace our tanks. Wouldn't it be simpler and cheaper to have some sensor on the dispenser which could read back pressure and automatically shut off?
