Has anyone ever purposely or accidently completely run one tank dry in flight? (Hopefully you've never run TWO tanks dry). How many "sputters" did you experience before you switched tanks and had the engine going normal again? Did the engine stop completely? How fast were you able to restart the engine? I don't plan on getting to that point but still want to be prepared in case of an emergency. Was it simply switch tanks, boost pump and back in business?
