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.
