Fuel pump actuator
The fuel pump actuator moves the regulating sleeve of the fuel pump and thus controls the fuel
quantity, refer to
. Each fuel pump is connected to its related actuator (for an X92
engine two fuels pumps are connected to there related actuator).
The ECS controls the fuel pump actuators. During operation the fuel pump actuators move at the
same time. Each fuel pump actuator has an overload protection. Thus you do not have to
disconnect a fuel pump actuator, if the regulating sleeve of a fuel pump cannot move.
