A gasser is not the answer if You are looking to store fuel either. The gas of recent years has had a very limited shelf life before varnish and other nasty things happen to the stored fuel. A friend of mine has a small engine repair shop, in recent years he has seen more problems that are caused by "Bad Gas" than ever before.
I add stabilizer to every can of gas that I have as soon as I fill it no matter how quickly I plan on using it. Since I have been using stabilizer I have not had any (Knock on Wood) fuel related problems in small engines and seasonal equipment.
