I think that your tanks will not feed evenly because of little
differences in the way the lines run and venting. You will also lose
the ability to run one tank dry to extend your range. On my murphy
rebel one tank feeds a lot faster than the other one when I'm running
on both.


Very dependent on how far below the tank outlet the two lines/valve
connects the two feed lines,,,,,,,,,,

a connection that is level with the tank outlets will very likely have
trouble feeding both tanks evenly,

a much lower connection won't care,,,,,,,,,

that may usually be the case but on my plane the connection is at the
firewall just ahead of the gascolator. thats almost 3' difference in
height. When I did my fuel flow test the tanks flowed the same amount.



I'd bet mine would too, on the ground,

but in the air, they were several inches different, and with a tank that
is pretty thin, it is a bunch of fuel, or air, since the pump will suck
air from the empty tank rather than fuel from the partially full one,

I solved it by installing two small forward pointing tubes that mount on
the caps,,,,
