Al,
    That was my first thought to just drain the smaller tank into the  
larger with a simple 1/4 turn on/off but I would have to run the main  
at least 1/2 empty for this to work. I cannot fly ackro with less than  
6 gallons in the main tank. I cannot fly ackro at all with fuel in the  
smaller tank so by the time the smaller tank emptied I would have  
little fuel remaining in the larger tank. I even considered a small  
transfer pump to fill the larger tank but I am again creating  
complexity.
All input here is welcome :))
Thanks,
