If returning fuel is released into the atmosphere,
its vapors can ignite in the presence of any igni-
tion source. Do not expose the fuel to, or work
with the fuel system near, open flame or intense
heat. To do so could cause fire, possibly resulting
in serious personal injury or property damage.
1. Drain off some fuel by loosening the vent plug
and opening the drain valve.
2. Disconnect the water sensor and heater connec-
tions if equipped.
3. Remove the bowl by turning counterclockwise.
4. Remove the element, bowl O-ring, and element
o-ring. Dispose of them in an environmentally
acceptable manner.
5. Thoroughly clean all of the threads and sealing
surfaces. Even a small amount of dirt will prevent
the fuel/water separator from sealing, and an air
leak may result.
6. Apply a coating of clean fuel or motor oil to the
new O-ring and to the new element o-ring.
7. Insert the new element into the upper housing.
