SERVICE AND MAINTENANCE
4. Pull out the filter element downward
and remove the O-ring.
Use a clean cloth to wipe off any
foreign matter that has accumulated
on the inside surface of the filter body.
ADVICE
• Do not use compressed air to
remove foreign matter. Use a clean
cloth instead. Air blowing may bring
foreign matter into the fuel passage,
which could cause the engine to
malfunction.
5. Attach the new O-ring to the filter
body, making sure that it is not
damaged by the screw threads.
6. After lightly coating the inner and
outer gaskets of the new filter element
with diesel fuel, insert the element
until it touches the filter body.
ADVICE
• Do not allow foreign matter to get
into the 4 holes next to the inner
gasket.
7. After lightly coating the inner surface
of the element case or the O-ring with
diesel fuel, turn the element case
clockwise until it touches the filter
body.
If the element case end fails to touch
the filter body, the filter element has
not been inserted fully. Reinsert the
element while turning it.
