ELECTRICAL SUBSYSTEM
All electrical power distribution, control and monitoring is performed by the electrical subsystem. The subsystem consists of
the system battery, the control panel, the alternator, the voltage regulator, the engine starting motor, the auxiliary pump,
various engine and pumpage sensors, controls, and the interconnecting cables.
DEFUELING SUBSYSTEM
The defueling subsystem consists of the auxiliary pump module connected in the AAFARS to pump fuel from system
components to the fuel drums. Figure 5 illustrates one common configuration. The auxiliary pump is a rotary vane, positive
displacement pump capable of a maximum flow rate of 15 gpm. It is equipped with two-inch unisex couplings at inlet and
outlet, allowing it to be connected directly to almost every system component. It may be used to defuel the entire system, or
an individual component such as the liquid fuel filter-separator or even a single length of hose.
