Are you sure that piece of metal with a ball in it wasn't the anti-backflow valve? I haven't looked on my Outback but my cruiser has the valves on both tanks - basically they are supposed to prevent a fire from getting to the tank if you're unfortunate enough to have a fire onboard. If your mechanic "lodged" the ball out of the way, and if it was a faulty ABF valve then you may have a non-functional but required and critically important valve.
