Our fuel systems are very critical but flying the plane is more so.  How
about a pump in each tank and a common return to both tanks??  No valves.

I agree that John Denver was killed by doing several bad things, and that having
the fuel selector on the firewall was only one of them. I tried to tee the
return fuel line so that it would return to both tanks, but it didn't take only
a few minutes until the left tank had most of the fuel in it. I think the
hydraulic balance is too hard to achieve, plus  you've got to deal with tank
venting differences. Better to have a positive return to the originating tank
IMHO.
