Here is the tank I use to carry an extra 4.5 gallons of fuel for long cross country flights in my Sonerai. It is a "5 gallon moon tank" I bought on eBay. I made the bracket to mount it to the front seat. Fuel is transferred to the main tank via a fuel line with a quick disconnect and a facet pump. When the fuel in the main tank drops below 5 gallons, I can switch the pump on and it takes about 12 to 13 minutes to transfer all the fuel. It takes about 5 minutes to install or remove the tank.
Note: I use nylon webbing to hold the tank in place while flying, not the bungee cords in the picture.
