Reference the header tank vs wing tank discussion. Just like most things on the KR, there are many ways to do things.
My KR2S has just a header tank with approx 16 gallons. My reason not to put fuel in the wings was complexity. I simply didn't want to add a fuel pump and tanks to the wings. The 16 gallons gives me 3 hours of flight time with reserves. I have plenty of range for what I desired to build the airplane for - local fun flying. My fuel tank is integral to the forward deck and is removable by mounting screws that are attached to the sides/firewall/and near the instrument panel. My CG is calculated so I know that my fuel causes the CG to move approx 1.6 inches as the fuel is burned off. I can still carry a 220 passenger and stay within the rear CG limit, I weigh 160 pounds.
