If I want fuel from the left, I turn on the left pump, and so with the right. If I want lots of fuel fast, I turn on both. I'm sure this, or simple check valves would do the trick if you just want wing tanks. With check valves, there wouldn't be any flow from one tank to the other. Not that there would be much anyways... It seems people forget that in a co-ordinated turn (even a steep one) centrifical force keeps the fuel at the root. A hard slip is another matter. Marv, I don;t remember if you're using fuel injection... if so, you may want to look into a surge tank of some type. (I already have one with the header tank.) Even a smaller (say 5 gal) header tank might be a thought.
