Joe,
This was as simple as I could come up with. Has worked fine for 240 Hrs. No selectors to forget. I have a 3-minute timer on the transfer pump which transfers 1 gal/min, and just punch the button when 3 gal will put me back in lateral trim. (I also have a panel switch to turn the pump on if needed, but I was always forgetting to turn it OFF when the fuel was balanced.)
I always plan my flying as if I only have what is in the right tank, so if rough terrain approaches, there tends to be more than an equal amount in the right tank. With this system, you can drain the left tank completely, and then if the engine coughs, you KNOW you have used it all!
I only use both pumps for takeoff and landing. I always cruise on the same one, so the other pump/filter gets very little use. That becomes my spare if the main pump or filter takes early retirement.
