WARNING
Pump Module (para. 4.8. 10)
Fuels are toxic and flammable. Do not get on person
or clothing. Work in well ventilated area. Do not
smoke. Ensure equipment is well grounded.
0Death or personal injury may result from the explosion of fuel fumes exposed to an open
flame or spark, or to static discharge. Do not permit smoking, any open flame, or spark
producing equipment within fifty (50) feet (15.24 m) of the auxiliary pump during repair.
•
Rubber gloves should be worn when handling fueling system components due to the toxic
effects of some fuel additives.
NOTE
•
This procedure assumes that the auxiliary pump has been defueled. However, some
residual fuel may remain due to normal drainage after defueling.
•
Inspect all components as they are disassembled. Repair is limited to replacement of
unserviceable components discovered during disassembly.
a. Disassembly
and Inspection.
(1) Remove four bolts (1) that attach pump rotor cover (2). Remove cover (2).
(2) Remove and discard rotor cover gasket (3).
NOTE
A new pump rotor vane is 7/16 in. high. Replace vane if height is 9/32 in. or less. A vane
that does not make good contact with pump chamber will cause loss of suction.
(3) Remove the five vanes (4) from rotor (5). Inspect vanes (4) for damage and wear.
