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.
