WARNING:

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

FL-30, "General Precautions"

.

REMOVAL

1.

Release the fuel pressure from the fuel lines. Refer to 

ECK-153, "Work Procedure"

.

2.

Check fuel level on a level ground. If the fuel level is at 1/2 or higher, drain enough fuel so that the level on
the fuel gauge is at half or below.
• This is to prevent overflow of fuel from the tank when the  fuel level sensor unit, fuel filter and fuel pump

assembly is removed 

• In the event of malfunction in fuel pump, insert a hose measuring less than 20mm (0.79 in) in diameter

into fuel filler tube through fuel filler opening to draw fuel from filler tube.

- Disconnect fuel filler hose from fuel filler tube. Refer to 

FL-10, "Exploded View"

. 

- Insert hose into fuel tank through fuel filler hose to draw fuel from fuel tank.

3.

Disconnect batterie cable from negative terminal.

4.

Open fuel filler lid and filler cap to release the pressure inside fuel tank.
