The container within a container prevents the major sloshing of fuel across the tank....

On some of my race cars....we used an external sump for the fuel.....so an additional tank that the fuel pumps from the cell pumped into....then, two more fuel pumps pumped the gas forward to the Carb.....and if you really wanted to get tricky.....put the additional tank inside of your fuel cell and fill it first.....then when you fill the fuel cell they can only pump in the 22 gallons you are suppose to have......(not counting the extra 1 or 2 gallons hidden inside the fuel cell.......).....Unfair Advantage
