    Hi, Tracy....thank you for that detailed explanation.  The light finally
came on, and I understand it now. Unfortunately, I have only had carburetors
in the past, and the EFI is all new to me.  One last question came to mind
as I was imagining the fuel returning to the sump tank.  Is it normally a
large volume of fuel that returns to the tank, or just a trickle.  I ask
that because I need to consider how large of a sump tank to incorporate into
my fuselage.  Thanks again, Tracy.    Paul Conner
