FUEL LEVEL SENSOR UNIT, FUEL FILTER AND FUEL PUMP ASSEMBLY

REMOVAL

WARNING:

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

FL-3, "General Precau-

tion"

.

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-49, "Rotation"

.

3. 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.

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. Disconnect the fuel filler hose from the fuel filler pipe.
c.

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-495, "Fuel Pressure Check"

(VQ40DE),

EC-

958, "Fuel Pressure Check"

(VK56DE).

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. On models equipped with fuel tank shield, remove the four bolts and remove the fuel tank shield.
8. Remove the propeller shaft. Refer to

DLN-325, "Removal and Installation"

(2S1330),

DLN-336, "Removal

and Installation"

(2S1350).

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

12. Disconnect the fuel level sensor, fuel filter, and fuel pump

assembly electrical connector, and the fuel feed hose.

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.
