why? (Those 12v pumps would empty a 20 gallon tank in ~500ms)ND4SPDSHO : Anyone ever try putting a gas station type setup in their trailer? Obviously not that big, but maybe something like a 20 gallon can with a submersible electric motor and a nozzle for easy re-fueling.
whatever, have fun...ND4SPDSHO : That depends on how big of a pump you get. I've use 110V pumps that would empty a 200,000 gallon pool in 3 days. I've also use 110V pumps that would take 2 weeks. Volts have nothing to do with it, it's the amperage of the motor.
