8. Remove lock ring for fuel level sensor unit, fuel filter and fuel

pump assembly using Tool (A) by turning counterclockwise.

9. Remove fuel level sensor unit, fuel filter and fuel pump assembly.

CAUTION:

• Do not bend float arm during removal.

• Do not allow contaminants to fall inside of the fuel tank.

• Do not cause impacts such by dropping when handling components.

INSTALLATION

Installation is in the reverse order of removal.

• Install the fuel level sensor, fuel filter, and fuel pump assembly with

the fuel feed tube (C) facing the front of the vehicle as shown. Use

a new O-ring.

CAUTION:

Do not reuse O-ring.

• Connect the quick connector as follows:

- Check the connection for damage or any foreign materials.

- Align the connector with the tube, then insert the connector straight

WARNING:

Read “General Precautions” when working on the fuel system. Refer to 

FL-2, "General Precaution"

.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.

REMOVAL

1. Check the fuel level with the vehicle on a level surface. If the fuel

gauge indicates more than the level as shown (1/2 full), drain

the fuel from the fuel tank until the fuel gauge indicates a level at

or below as shown (1/2 full). 

• In case the fuel pump does not operate, use the following pro-

cedure.

a. Disconnect the fuel filler hose from the fuel filler tube.
b. Insert fuel tubing of less than 20 mm (0.79 in) diameter into the

fuel filler tube through the fuel filler opening to drain fuel from the

fuel filler tube.

• As a guide, if the fuel tank is full the fuel level reaches or is

less than the level on the fuel gauge as shown, when approxi-
mately 20-1/2   (5-3/8 US gal, 4-1/2 Imp gal) of fuel is drained from a full fuel tank.

2. Release the fuel pressure from the fuel lines. Refer to 

EC-135, "Work Procedure"
