Recently i build a motorized gas bicycle that i plan to use to do uber eats. Im ignorant when it come to how i should go about storing my gas. I got 2 of those midway 2 gallon gas cans, one for pure gasoline and the other for gas mixed with oil. With my gas cans am i supposed to close the lid super tight or let it gas out? Will vapors build up inside the can and make it blow up? Because my landlord is a snob he locked the garage and isnt allowing any of his tenants to use it, will it be a problem if my gas cans are left outside with gas in them? Im a complete noob at storing gasoline and im not trying to blow my entire neighborhood up or have my fuel go stale quickly.
