a. Using a screwdriver, separate the snap fit portion of bracket in
numerical order as shown in the figure.
CAUTION:
Put cloth or similar one on the edge of screwdriver not to
damage the inserted portion.
b. Pull out fuel pump, and disconnect harness connector.
2. Separate fuel filter and fuel level sensor unit as follows:
a. Fit a used O-ring into space between fuel level sensor unit and
fuel filter to release tabs.
NOTE:
For reference when reassembling, put a mating mark on outer
edges of fuel level sensor unit and fuel filter with some means
which cannot be erased by fuel.
b. Insert screwdriver to the gap between fuel filter and fuel level
sensor unit to separate them.
CAUTION:
Put cloth or similar one on the edge of screwdriver not to
damage the inserted portion.
3. Remove pressure regulator from fuel filter as follows:
a. Open and remove the clip.
b. Pull pressure regulator straight out during removal.
CAUTION:

Avoid impacts such as falling during removal.

Do not disassemble or adjust.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Install fuel filter and fuel pump with the tabs aligned. Make sure a click sound of secure engagement is
heard.

Securely connect harness connector of fuel pump.

Install pressure regulator O-ring.
CAUTION:

When replacing, always use new O-ring.

Handle it with bare hands. (Do not use gloves.)

Visually check the O-ring, mounting parts and mating parts for foreign materials and flaws.

Before installing, apply new engine oil.

To avid damage, do not apply an excessive force (pulling or starching).

REMOVAL
WARNING:
Be sure to read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
1. Perform the steps 1 to 7 of “REMOVAL” in “ FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL
PUMP ASSEMBLY”. Refer to FL-4, "
REMOVAL" .
2. Drain fuel more from fuel tank if necessary.
CAUTION:
Because fuel tank forwardly inclines and becomes unstable when installing/removing, fuel should
be drained if found the remaining quantity.
3. Remove exhaust center tube and insulator. Refer to EX-2, "
EXHAUST SYSTEM" .
4. Remove propeller shaft. Refer to PR-3, "
REAR PROPELLER SHAFT" .

REMOVAL
1. Remove air duct, air cleaner case and mass air flow sensor assembly. Refer to EM-133, "AIR CLEANER
AND AIR DUCT" .
2. Remove fuel filter protector.
3. Disconnect fuel hoses at fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with fuel filter bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type fuel filter wrench (commercial service tool),
remove fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Note the following, and install in the reverse order of removal.

Replace O-ring on drain plug with new one.

Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.

After installation, bleed air from fuel line. Refer to FL-18, "Air Bleeding" .
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.

Start the engine and rev it up and make sure there is no fuel leakage at connections.

Air BleedingEBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel line as follows:

Move priming pump up and down to bleed air from fuel path.

When air is bled, pumping of priming pump becomes heavy stop
operation at that time.

Crank engine until it starts. Do not crank engine for more than
30 seconds.

If engine does not start, stop cranking and repeat step 1 above.

If engine does not operate smoothly after it has started, race it
two or three times.

If 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 confirm 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 FilterEBS00MRU
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:

Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.

Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mounting insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-18, "
Air Bleeding" .
5. Start engine and make sure there is no fuel leakage.
