Oops. Somehow my last msg got garbled amazingly. I am resending it in pure 
text mode (supposedly).

Thanks for the good ideas, guys. I plan to use a Suzuki 1300 automotive 
engine conversion. I think I understand the implications of each 
alternative mentioned. 

The 6-port valve would be a good where tank switching was used. I was 
wondering (hoping) a high wing would have allowed me to KISS things more 
by eliminating tank valve switching. 

For a header system I can imagine some sort of check valve. I expect there 
would always be some leakage so a separate fuel cutoff would be required 
upstream from the header when not flying. Is this feasible, advisable?

Starting from Tracys approach, would it be feasible to take the outlet 
from the tank without a return line and join it via a T with the main 
feed line from the other tank. A T rather than a Y would create a 
Bernoulli effect that would tend to increase fuel extraction from the tank 
without a return line --- theoretically. I would still need an equalizer 
line between the tanks to keep levels reasonably close. Or does an 
equalizer line not make things equal enough?

Thanks.
