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.
