Ed,
Have you ever had problems getting the electric fuel pumps to prime
following
an empty tank? What means do you use to get the fuel from the wings to
the
header tank?
Mark S.
No Mark, I have not.
The EFI fuel pumps will actually create sufficient suction that they
will pull from the low wing tanks even without a boost pump. However, should
an leak develop, it could compromise the "suction" therefore, I do use a
boost pump for take off and landing for safety sake. But, once the engine
is running the EFI pumps pull fuel from the wing tanks of my RV-6A with no
difficulty and I turn the boost pump off in cruise flight.
