Section XX. MAINTENANCE OF FUEL TRANSFER PUMP
4-52.
FUEL TRANSFER PUMP. The fuel transfer
pump (figure 4-31) has a DC operated motor and is
used to transfer fuel from an auxiliary source to the
generator set fuel tank. Pumping is automatically
controlled by a float level switch in the generator set fuel
tank when the FUEL PUMP switch on engine control
panel (see figure 2-1) is in the AUTO position. The
pump (16, figure 4-31) is mounted on the support
bracket (51) on the generator set base assembly.
a.
Inspection.
(1)
Inspect pump for leaks, loose connections,
dents, and cracks.
(2)
Remove
fuel
line
from
pump
inlet
connection and inspect filter assembly for
accumulated dirt, cracks, breaks which
would cause restriction to fuel flow.
(3)
Inspect the motor for overheating or other
visible signs of damage.
b.
Test. Transfer pump testing consists of an
operational test as follows:
(1)
Place
24V
DC
CONTROL
CIRCUIT
BREAKER on generator panel to OFF, and
FUEL PUMP switch on engine panel to OFF
position.
(2)
Disconnect hose assembly connected to
pump connector (10, figure 4-31).
(3)
Attach a length of hose of this connector
and place in a container of adequate size.
(4)
Connect an external fuel supply to the fuel
transfer pump connection on the outside of
the base assembly.
