This, but I'd add a can of berrymans, sea foam or the like to it when I filled it up. 3.5 years isn't too long with a pretty much sealed tank like on modern cars.
Doubtful you can siphon it due to an anti-siphon valve or screen.
You guys nailed it! I was only able to locate one Berryman's product - the carb and fuel cleaner - but I added that and 5 gals of fresh gas to the tank. After throwing in a new battery I hit the key and she started in two seconds. There were no misfires and no smoke out the pipe. The car had 51,098 miles and was parked four years, one month. Put air in the tires and they're holding it, but there are fine cracks on the sidewalls.
Right now I could use a leaf blower to clear the layer of dust from the motor.
