3. Using band-type fuel filter wrench (A) (commercial service tool),
remove fuel filter (1).
4. Turn fuel filter (1) upside down to drain fuel.
5. Remove drain plug (2) from fuel filter.
INSTALLATION
Note the following, and install in the reverse order of removal.
lReplace O-ring on drain plug with new one.
lScrew the fuel filter by hand until packing contacts sealing surface of fuel filter bracket. Then tighten it by
turning approximately 2/3 turn.
lInstall fuel filter (1), and tighten mounting nuts (2) to the speci-
fied torque.
lAfter installation, bleed air from fuel line. Refer toFL-5, "Air Bleeding".
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.
lStart the engine and rev it up and make sure there is no fuel leakage at connections.
Air BleedingEBS01E74
After fuel filter is replaced and after fuel system components are removed/installed, bleed air from fuel line as
follows:
lMove priming pump (1) up and down to bleed air from fuel path.
When air is bled, pumping of priming pump becomes heavy stop
operation at that time.
lCrank engine until it starts. Do not crank engine for more than 30 seconds.
lIf engine does not start, stop cranking and repeat step 1 above.
lIf engine does not operate smoothly after it has started, race it two or three times.

FUEL FILTER
lIf air cannot be bled easily (pumping of priming pump does not become heavy), disconnect feed-side of
hose between fuel filter and electronically controlled fuel pump. After that, operate priming pump and con-
firm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine
mounting insulator.
Draining Water from Fuel FilterEBS01E75
1. Prepare a tray (A) under the drain plug (1).
2. Loosen drain plug (1), and operate priming pump (2) to drain
water from fuel filter.
CAUTION:
lWater in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.
lDrained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mounting insulator.
3. Replace O-ring on drain plug with new one.
4. After draining, close drain plug to specified torque.
CAUTION:
If drain plug is tightened excessively, it may be damaged and fuel will leak.
5. Bleed air in fuel piping. Refer toFL-5, "
Air Bleeding".
6. Start engine and make sure there is no fuel leakage.Drain plug
