The tanks position becomes ultra critical when high levels of both +/- Gs are experienced in a flight. That 3/8" low tank becomes a 3/8" high tank with down elevator and the engine will sense the difference in head. You will know that your setup is good when theres no mixture change between max-G inside and outside manuvers.

Correct, but being 3/8" above or below will make little difference with G effect. It will vary with the fuel level in either case, and that would be a larger variable. Mounting it below the centerline, not necessarily exactly 3/8", is better than mounting it at the center line where you know the head will change when the vent goes from top to bottom. A uniflow would be even better, but only a regulated pump or regulator will get rid of head from G effect. IMO not a big problem.

All good observations and statements. How about a round tank,tapering to the rear, then have a ball swivel on rear. The front of tank would be allowed to rotate around to follow planes attitude. That way the tank/carb relationship would be constant. Anyway, keep smiling, it confuses 'em. Good luck, red

Hi!
Either using the Uni-fow set -up or using the ultimate tank , the Tettra "Bubbleless"! No more tank problem.
