Use a siphon hose (or tube) that is rigid, but still has some flexability to it. That way you can jam it down into the farthest reaches of your tank. Siphon as much out as you can (unless you want to take your tank completely off and tip it upside down). Then top it off with fresh fuel. Maybe think about putting in some of those drop ins. You know, the ones that are suppose to absorb water, and treat your gas at the same time.
Thats what I'd try first. Good luck.
