So how do the pumps work when you are running on all 16 injectors all the time? How or what is done concerning the pumps?

Think of the secondary pump as an auxiliary pump. It comes on when the ECM calcs a need for additional fuel. Otherwise, whether on 8 or 16 injectors, the motor uses the same amount of fuel and the primary pump can supply that amount. If you're running 16 injectors, the fuel delivery is basically shared equally by both injectors.
