Randy;

Is the positioning of the tanks such that you could gravity feed the small
tank into the big tank? Then you could return to the larger tank - and
eliminate the selector valve.

Gentlemen,
   Because a large majority of homebuilt problems are fuel related I  
am trying to make my system as simple as possible. This is a biplane  
with a 20 gal. and a 10 gal. tank in front of the inst. panel, RX-8  
engine.
The only "known" problem I have at the moment is my fuel return. I  
would like it to return to the main tank only. This would mean burning  
off 2-3 gallons from the main tank before switching to the 2nd tank.  
But, this might mean I am setting myself up for a future "pilot error"  
in fuel management. If I return to both tanks I would need another  
selector and cockpit control which is making the system more  
complicated and, again, potential "pilot error." So, suggestions . . .
Thank you very much,
Randy
