"Ken:
your flushing approach should be adequate. Some recent posts indicate some mebers have had a lot of success 'emptying' there tanks by running a low pressure air stream into the tank via the filler neck. the airflow evaporates any remaining fuel in a short period of time. If you go this route, remember the explosive nature of fuel and take the proper precautions.
If there is any remaining water in the tank, you can mix some alcohol with it and then pump it out and use the air method to evaporate it out, too.
If you have an access port on the tank, you can also open it out and blot out any remaining fluid. either approach isn't hard, they are just time consuming. That said, it is well worth the effort to get as much of that old stuff out as possible."
