Ever seen one of these

Had to cut an aluminum gas tank open in a boat, sure would have liked having that instead of the electric one I used with a fan blowing the fumes away. Picked up a bunch of silicone chunks in a fuel up at a marina on the west coast. They kept plugging the end of the fuel pick up, the only way to get them out was cut the 80 gal tank open then put a bulkhead over the opening.
