fuel pump

I have an IO360 ECI Titan engine on my airplane equipped with the auxillary fuel pump purchased from Vans. In every other airplane I have owned, the engine would run and idle properly with the electric fuel pump on. The RV8 will run, but it certaonly runs very rich and rough with the pump on. It will continue to run at idle with the mixture at idle cut off. I'd like to be able to run the pump on takeoffs and landings like in other airplane. Is this normal? Do I need to install a different pump?

Do you have the ECI fuel injection?

Link to Manual

The AE fuel injection system requires the use of
at least one boost pump. The primary
requirement is that the boost pump must produce
between 18-22 psi fuel pressure for emergencies
if there is a loss of pressure from the engine
driven fuel pump. Similar fuel injection systems
used in certificated airplanes also employ a low
pressure fuel pump (3-5 psi) for take-off and
high altitude operation.

CAUTION
Excessive operation of the high boost pump
will cause the engine to flood. Operation with
low boost at intermediate power settings may
require the engine to be leaned slightly to
provide smooth operation.

AE recommends using low boost pressure for
take-off. Low boost can also smooth out engine
acceleration when the engine is cold.
