If you are going
to have a boost pump (highly recommended if your RV-3 is using wing tanks)
--------------------

===>  Hi Ed.  So I guess they have more suction than advertised.  I will be
using wing tanks, with no header tank, so why do you highly recommend a
boost pump?  I don't see the purpose, especially if the EFI pumps are
located below the fuel level.
