As a California resident, I have a tiny amount of responsibility for the CARB requirements; as much as any other liberal voter in the state. I used to really hate CARB compliant gas cans. Two things changed my mind: the CARB white paper on the requirements and Justrite 7250120 and 7250130 gas cans.The 120 can has a 5/8" nozzle and the 130 a 1" nozzle. These are the best gas cans I have ever owned or used. CARB or not-CARB. They are not cheap, $65 from Amazon, but they are well worth it for being long lasting and easy to use. Not to mention a small contribution to improving the quality of the air we all breathe.
