Randy,
The simpler the better. Tracy's system is about as simple as you can get and has proven itself over many hours of flying. He has one EFI pump drawing and returning to main wing tank. Then he has a facet pump to transfer fuel from the second wing tank to the main wing tank. He runs the facet pump as needed to replace the fuel used from the main tank. No valves, minimal plumbing. If I were to do it over, I would copy Tracy's design.

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
