FUEL FILTER
Draining the Fuel Filter
NOTE:
The fuel filter should be drained after
every 100 hours of operation.
1. Make sure there is adequate fuel in the fuel
tank and close the fuel shutoff valve (1) in
Figure 3-7, (the handle should be pointing to
the "OFF" position). Remove the fuel
sediment bowl (2) in Figure 3-7.
2. Open the fuel shutoff valve until all water has
been removed and only fuel flows from the
filter base.
3. Install the fuel sediment bowl and bleed the
system as outlined in "Bleeding the Fuel
System."
NOTE:
Valve is shown in open position.
Changing the Fuel Filter
NOTE:
Change the diesel fuel filter after the first
50 hours of operation, then following every 200
operating hours thereafter.
1. Close the shutoff valve (the handle should be
pointing to the "OFF" position).
2. Remove the sediment bowl (1) in Figure 3-8,
by rotating the retaining nut (2) in Figure 3-8.
3. Open the fuel shutoff valve (3) in Figure 3-8,
to drain any remaining water from the tank.
4. Discard the old element (4) in Figure 3-8, and
install a new element.
5. Inspect the O-rings (5) in Figure 3-8, and (6)
in Figure 3-8, and replace if necessary.
6. Install spring (7) in Figure 3-8, between
bottom of element and bowl.
7. Install and securely tighten the sediment
bowl.
8. Open the fuel shutoff valve (the handle
should be pointing to the "ON" position) (3) in
Figure 3-8, so fuel will flow to the filter.
9. Bleed the fuel filter and injection pump as
described next in "Bleeding the Fuel
