water and sediment in the bowl (2). Also
drain the fuel in

lter (3) in order to remove it.
6. Install the bowl (2) to the bottom of new
fi
lter. Always replace the O-ring seal (4).
7. Apply oil to seal surface during installa-
tion. Make the seal and

If the bowl (2) was over-tightened, the
O-ring seal might be damaged and fuel
leak could result. If the bowl (2) was not
tightened enough, fuel will leak through
the gap with O-ring seal. To prevent such
problems, always tighten it to the speci
fi
ed
torque.
8. Clean the
fi
lter seat. Add clean fuel to new
filter. Apply a thin layer of oil to the seal
surface and install the filter to the filter
seat.
Always prepare your machine as required
and lock/tag it out before proceeding.
