How to drain a tank

I'm trying to drain it fully so I can air it out and make sure it's free of water before refilling with fresh gas. Trouble is that the filler neck is not the lowest point when I invert it so I'm never going to get all the gas out. Is there a trick to this that's escaping me?

You could accomplish the same thing with a manual pump, you'd just have to mate up some extra hose to fit your need. Duane G Winter 1984 BW Sport 15 Center Console

With tanks that you cannot get the last drop out of I use a flexible grabber tool with a wads paper towel on the end. It will absorb the last few ounces of gas and you can just keep using fresh paper towels until you get it all. http://www.idealtruevalue.com/servlet...067/Detail The technique also has the advantage of allowing you to swap the inside of the tank out and examine what comes out on the paper towel. I lay the soaked paper towels out in the driveway and let them evaporate before throwing them in the trash. Gasoline is very volatile so it does not take long.
