One main tank that will free flow into the lower header tank.
The lower tank is approximately 6 Gallons and will need to have an Aerobatic inverted system installed. This means it will have a clunker in the middle heading to the Gasolier and two filler tubes from the main Tank.
I will have standard NO. 6 fuel fittings installed. I'll probably use standard 1/4" pipe fittings in the lower part of the main tank and the upper side of the header tank.
Working on the designing of this although I have the size laid out.
