Gordon,
I have a 12V Dukes Boost pump between the Andair valve and the inlet to the
two EFI pumps.  I doubt that I need it, but it came with the kit.  I just
looked and the boost pump is almost $1800!  I should have sold it and not
installed it!  What the boost pump will do in my installation is cure vapor
lock prior to the Gascolator and EFI pump inlets, should that occur.

Gordon,

I'm using twin EFI high pressure electric pumps pumping through two GM
EFI fuel filters, both in parallel.  The second, or backup pump, is
controlled by a pressure sensor & relay.  If the pressure drops below
30 psi the second pump automatically kicks on.  Both pumps are
downstream of a 6-port Andair valve which determines which tank I'm
drawing from.  This is for a low-wing a/c.
