I Tee-ed my fuel return and transfer lines together and have just one 
return/transfer line to the supply tank as you describe and it's been 
working well for my first 30 hours of flight.  As you stated you will 
need the check valve inline with the facet pump, my first tests were 
without one and I was getting some fuel getting past the facet pump and 
flowing to the transfer tank.
