Checking Fuel Lines

EBS00QUC

Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.

REMOVAL

WARNING:

Follow the “General Precautions” before working on the fuel system. Refer to 

FL-2, "General Precau-

tions"

 .

1.

Remove the fuel filler cap to release the pressure from inside the fuel tank.

2.

Remove the LH rear wheel and tire. Refer to 

WT-7, "Rotation"

 .

3.

Check the fuel level on level gauge. If the fuel gauge indicates
more than the level as shown (full or almost full), drain the fuel
from the fuel tank until the fuel gauge indicates the level as
shown, or less.

NOTE:
Fuel will be spilled when removing the fuel level sensor, fuel fil-
ter, and fuel pump assembly for the fuel level is above the fuel
level sensor, fuel filter, and fuel pump assembly fuel tank open-
ing.

As a guide, the fuel level reaches the fuel gauge position as
shown, or less, when approximately 15   (4 US gal, 3 1/4 Imp
gal) of fuel are drained from the fuel tank. 

If the fuel pump does not operate, use the following procedure to drain the fuel to the specified level.

a.

Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel filler pipe through the fuel filler
opening to drain the fuel from fuel filler pipe.

b.

Remove the fuel filler pipe shield.

c.

Disconnect the fuel filler hose from the fuel filler pipe.

d.

Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.

4.

Release the fuel pressure from the fuel lines. Refer to 

EC-79, "FUEL PRESSURE RELEASE"

 .

5.

Disconnect the battery negative terminal.

6.

Disconnect the lower fuel filler hose from the fuel tank, the EVAP hose, and the vent pipe quick connector.

Disconnect the fuel feed hose from the molded clip in the side of the fuel tank.

Disconnect the quick connector as follows:

Hold the sides of the connector, push in the tabs and pull out the tube.

If the connector and the tube are stuck together, push and pull several times until they start to move.
Then disconnect them by pulling.

CAUTION:

The quick connector can be disconnected when the tabs
are completely depressed. Do not twist the quick connec-
tor more than necessary.

Do not use any tools to disconnect the quick connector.

Keep the resin tube away from heat. Be especially careful
when welding near the tube.

Prevent any acid liquids such as battery electrolyte, from
getting on the resin tube.

Do not bend or twist the resin tube during connection. 

Do not remove the remaining retainer on the hard tube (or
the equivalent) except when the resin tube or the retainer
is replaced.

When the resin tube or hard tube, or the equivalent, is 
replaced, also replace the retainer with a new one (semi-
transparent colored retainer).

To keep the quick connector clean and to avoid damage
and contamination from foreign materials, cover the
quick connector with plastic bags or suitable material as
shown.      

7.

Remove the four bolts and remove the fuel tank shield.

8.

Remove the propeller shaft. Refer to 

PR-9, "REAR PROPELLER SHAFT"

 .

9.

Support the fuel tank using a suitable lift jack.

10. Remove the three fuel tank strap bolts while supporting the fuel

tank with a suitable lift jack.

11. Remove the fuel tank straps and slowly lower the fuel tank to access the top of the fuel level sensor, fuel

filter and fuel pump assembly.

CAUTION:

Do not lower the fuel tank too far to prevent damage to the fuel feed hose and the fuel level sensor,
fuel filter and fuel pump assembly connector

16. Remove the fuel level sensor, fuel filter, and fuel pump assem-

bly.

CAUTION:

Do not bend the float arm during removal.

Avoid impacts such as dropping when handling the com-
ponents.

INSTALLATION

Installation is in the reverse order of removal.

Connect the quick connector as follows:

Check the connection for any damage or foreign materials.

Align the connector with the pipe, then insert the connector straight into the pipe until a click is heard.

After connecting the quick connector, make sure that the con-
nection is secure by checking as follows:

Pull the tube and the connector to make sure they are securely
connected.

Visually inspect the connector to make sure the two retainer tabs
are securely connected.

CAUTION:

Do not bend the float arm during installation.

Avoid impacts such as dropping when handling the compo-
nents.

INSPECTION AFTER INSTALLATION

1.

Turn the ignition switch ON but do not start engine, then check the fuel pipe and hose connections for
leaks while applying fuel pressure.

2.

Start the engine and rev it above idle, then check that there are no fuel leaks at any of the fuel pipe and
hose connections.
