FUEL PUMP SEDIMENT BOWL
Fuel presents the hazard of fire or ex-
plosion which can cause severe personal injury or
death. Do not permit any flame, spark, pilot light,
cigarette, arc-producing equipment or other ignition
source near the fuel system. Keep an ABC type fire
extinguisher nearby.
Every 100 hours, remove the sediment bowl from the fuel
transfer pump and filter body (Figure 7-5). Clean out any
water or particulate present in the bowl and filter. When
re-installing the sediment bowl, make sure the filter and
gasket are in place.
