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 connec-

tion 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.

REMOVAL

WARNING:

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

FL-2, "General Precau-

tion"

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

Remove the LH rear wheel and tire. Refer to

WT-36, "Rotation"

Check the fuel level on level gauge. If the fuel gauge indicates
more than the level as shown (half "1/2"), 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 lower fuel filler hose if the
level is above "1/2".
• As a guide, the fuel level reaches the fuel gauge position as

shown, or less, when approximately 43 (11 3/8 US gal, 9 1/2
Imp gal) of fuel are drained from the full fuel tank.

• If the fuel pump does not operate, use the following procedure

to drain the fuel to the specified level.

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.

Disconnect the fuel filler hose from the fuel filler pipe.

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

Release the fuel pressure from the fuel lines. Refer to

EC-481, "Fuel Pressure Check"

(VQ40DE),

EC-

948, "Fuel Pressure Check"

(VK56DE).

Disconnect the battery negative terminal.

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).
