Trying to get a few of the details ironed out.  I am building an RV7 with a
rotary engine.  After much thought I decided Tracy Crooks fuel system would
work very well.  The only other alternative I considered meant buying an
Andair fuel valve and they are just too expensive for a manual valve.  My
question is, if I plumb the transfer line (one tank to the other) into the
fuel return line (coming from the engine) will the facet fuel pump have
enough pressure to over come the returning fuel?  Is the returning fuel
under any pressure at all or just flowing back to the tank?  I do know I
will have to have a check valve to prevent fuel returning to the wrong tank.
Thanks in advance.
