This plastic can which is approved by the Califoria Air Resources Board leaks. The specially shaped seal deteriorated after about a year of service. Replacements are unavailable. The nozzle is too short to reach safely into the gas tank and the plastic container is easily damaged plastic construction. During transport the nozzle cannot be placed in a safe condition. It sticks up in the one available fixed-position. It is dangerous, but the fact that the manufacturer does not respond to email inquires for replacement seals means the can is useful for about a year.
