gas tank dilemma..........

You don't want it to sit empty, or at a half. You want it full. Simply treat with a fuel stabilizer and use ethanol free fuel if you can find it. The ethanol fuel will absorb so much moisture in half or 1/4 filled tank that eventually crap will be growing in the fuel. If you are 100% dead set on draining the fuel, just throw on a non-vented gas cap...disconnect the fuel line at the fuel pump...attach a "line extension" into whatever fuel container you wish...use an air compressor on the vent line back at the tank, she will gladly piss fuel right into you container of choice. What little fuel is left in the tank might sour, but top it off with a few fresh gallons and you are good to go. Hmmm. Except for the rust that now builds up inside the tank now that it's exposed to air instead of submerged in fuel. Did I mention a full tank of treated non-ethanol fuel is the way to go?
