MAINTENANCE
There is a new-style pre-filter with a
stepped-down diameter at the bottom of the filter.
The earlier-style filter has straight sides with a
larger bottom diameter which requires an adapter
to attach the fuel/water separator bowl to the
filter. When replacing the previous straight-sided
filter with the current stepped-down version, the
adapter is not used. However, do not discard the
adapter as it can be used should inventory of the
earlier-style filter still be available.
9. If necessary, replace the full-flow filter. See
the following instructions.
10. Connect the electrical cable.
11. Start the engine and run at idle for five
minutes to fill the filter with fuel.
12. Check for leaks.
Full-Flow Filter Replacement
To replace the full-flow filter:
1. Make sure the filter casing is thoroughly
cleaned. If not already done, wash the area
around the filter mounting adapter with a
suitable solvent and blow dry with
compressed air.
2. Put a suitable container in place to collect
spillage.
3. Using a filter wrench, remove the filter
casing from the mounting bracket and
discard it.
4. Apply a thin film of clean engine oil to the
sealing gasket of the new filter.
5. Screw the new dry filter in place and tighten
an additional 3/4 to 1 turn by hand after the
gasket contacts the base.
6. If necessary, replace the water separating
pre-filter. See the preceding instructions.
7. Use the hand primer on the fuel filter
housing to bleed the fuel system.
8. Start the engine and run at idle for five
minutes to fill the filter with fuel.
9. Check for leaks.
Severe engine damage may be caused by
attempting to prime the fuel system using an
auxiliary pump or by applying air pressure in the
fuel tank. These techniques may destroy seals
that prevent fuel from leaking into the crankcase.
