Frank, header tanks are installed as a nicety to avoid having to plumb a return line all the way back to one of the existing fuel tanks and to avoid that issue which Beech created for so many of their airplanes. (I'm thinking of the need for some airplanes to burn fuel out of a particular tank for a stated period of time in order to create space for the returned fuel. C-400 series does the same thing with tip tanks, which are the main tanks. They must be used first, in order to avoid overfilling them with returned-fuel, in-flight. A header tank solves both issues.)
