I've got like six plastic gas cans. None of the lids are interchangable. They all leak. Getting gas out of them is like trying to milk a bull. Some dam near need four hands to get them to work. I contacted the manufacturers, most of whom are in Canada, and they all say these are the specs they are required to build to per the USA. They all say they are stupid as all get out, but can't change. Why bother? They're all mostly useless. They don't pour right. They don't breathe right, and I end up with gas everywhere, including my hands and all over my generators. I hate stupidity. I miss the old days, when things didn't have to be idiot proof. ARRRRRRRRGH!
