We use a 3.5 gallon (sometimes a 6 gallon) plastic fuel tank secured in the back of the cockpit. We use a rubber fuel hose with a rubber bulb pump to pump fuel from the plastic tank through a modified fuel cap on the motor and periodically fill the tank on the motor. The cap is modified by drilling a hole in the middle of it and screwing in a fitting to take the rubber hose. We usually get a couple of hours on a tank in the motor so end up pumping it full every hour or so if we are motoring continuously. Usually takes 10 to 30 squeezes of the bulb to fill the tank back up. It is a system I learned about in this forum and works great.
