FUEL DELIVERY PUMP AND FUEL FILTER

Precautions

ALWAYS disconnect battery cables from battery BEFORE working on fuel system
to prevent fire. This eliminates the engine wiring as a potential source of ignition.
FIRE HAZARD: Be careful when changing fuel system components; diesel fuel is
flammable. Fuel leakage from any part of the fuel system can be a fire hazard which
can cause serious bodily injury or death. Ensure that ignition key is OFF. Do NOT
smoke or allow sources of open flame in the area while changing fuel system com-
ponents. Do NOT allow fuel to come into contact with any hot surface which may
cause it to ignite.
FIRE HAZARD: Wipe up any spilled fuel immediately. Dispose of rags appropriately.
Dispose of fuel soaked rags, paper, etc. in an appropriate air tight, fire retardant
container. Fuel soaked items may spontaneously ignite and result in a fire hazard
which could cause serious bodily injury or death.
Avoid diesel fuel fire or explosion. Improper installation of brass fittings or plugs
into fuel filter base can crack casting and/or cause a fuel leak.
