HOW-TO SECTION
Replace Fuel/Water Separator
Element
If an optional primary filter/water
separator is installed in the fuel system
piping, replace the element as follows:
1. Shut down the engine and allow
it to cool.
2. With the engine at ambient
temperature and cool to the touch,
place a suitable container under
the filter.
3. A fuel shutoff valve may be
installed on the discharge side
of the fuel/water separator. If
installed, turn the handle on
the shutoff valve to the closed
position (perpendicular to the
valve).
4. Drain off some fuel by opening
the drain valve.
5. Using a strap wrench, remove
the element and bowl together,
then remove the bowl from the
element. The filter and bowl
have right-hand threads, so turn
counter-clockwise to remove.
6. Clean the bowl and the O-ring
seal.
7. Apply a light coating of clean
fuel or grease to the O-ring seal,
thread the bowl onto the new filter
and tighten by hand.
