OPERATING THE FUEL FILTER/WATER SEPARATOR WITH NO ELECTRICAL POWER
Only one fuel transfer pump at a time may be operated while using the fuel filter/water
separator. Attempting to use two fuel transfer pumps will exceed the capacity of the fuel
filter/water separator and could result in damage to the fuel filter/water separator or to
the fuel transfer pumps.
The fuel filter/water separator is capable of normal operation without electrical power.
However, the fuel filter/water separator's sump must be frequently checked for water
