As the title says, I have to pump out about 15 gallons of old gas from my inboard boats fuel tank that had been sitting in storage in NY for the last 2 years. I finally got it down here, and am dreading the job, as I've been looking at the boat for the last 3 months out in my driveway. I know it's got plenty of water in it too, because just trying to pump it out I got a good gallon of water out of it running it through a water separator. So, where do I get rid of this stuff?
