Sierra Tools Battery-Operated Liquid Transfer Pump, Model# JB5684
You can buy all kinds of liquid transfer pumps, but without power they don't help you at all. That's why this battery-operated pump is such a smart choice. It can pump gas, water, oil and other non-corrosive liquids at a rate of 5-6 quarts/minute, making it a smart choice for the garage, aquarium, basement, shop or yard, especially if the power is out. Requires 2 D cell batteries (not included).
