warning

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

REMOVAL

2WD

caution

Perform the operation with vehicle on level ground.

1. Release fuel pressure. Refer to Work ProcedureWork Flow

2. Open fuel filler lid.

3. Insert a general purpose pipe with the dimensions shown in fuel filler cap less unit and release the pressure inside the fuel tank.

A	: Over Φ 16 mm (0.63 in)
B	: Φ 21.0 mm (0.83 in)
C	: 150 mm (5.91 in)

note	Insert and hold 80 mm (3.15 in) from the end of the general purpose pipe into the fuel filler port.

4. Check fuel level on a level ground. If the fuel level is 7/8 of the fuel tank (full or nearly full), draw appropriate amount of fuel from the fuel tank.

Guideline

: Draw approximately 15 liters (4 US gal, 3-2/8 Imp gal) from a full-tank condition.

In the event of malfunction in fuel pump, insert a hose measuring 16 mm (0.63 in) in diameter into the filler opening to draw approximately 15 liters (4 US gal, 3-2/8 Imp gal) fuel.

5. Remove second seat.

6. Remove inspection hole cover.

Using a screwdriver, remove it by turning clips clockwise by 90 degrees.

7. Disconnect harness connector

and quick connector

	: Fuel feed tube
	: Fuel level sensor unit, fuel filter and fuel pump assembly
