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, "

If necessary, repair or replace damaged parts.
General PrecautionsEBS00BKI
WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: INFLAMMABLE” sign in workshop.
Be sure to work in a well-ventilated area and furnish workshop with a CO2 fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and spark away from work area.
CAUTION:
Before removing fuel line parts, perform the following procedures:
–Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
–Disconnect negative battery terminal.
Always replace O-ring and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure
quick connectors are secure.
Ensure that connector and resin tube do not contact any
adjacent parts.
After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–Start the engine and rev it up and check for fuel leaks at

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.
