WARNING:
Be sure to read “General Precautions” when working on the fuel system. Refer to FL-3, "
General Pre-
cautions" .
1. Check fuel level on fuel gauge. If gauge indicates more than the
level as shown in the figure (full or almost full), drain fuel from
fuel tank until gauge indicates level as shown in the figure or
below.
NOTE:
Fuel will be spilled when removing main and sub fuel level sen-
sor units for the top of the fuel is above the main and sub fuel
level sensor units installation surface.

As a guide, fuel level becomes the position as shown in the
figure or below when approximately 15 (13-1/4 Imp qt) of
fuel are drained from fuel tank.

In case fuel pump does not operate, perform the following
procedure.
a. Insert fuel tube of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
draw fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-11, "
FUEL TANK" .
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel from fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-48, "
FUEL PRESSURE RELEASE" (WITH
EURO-OBD) or EC-510, "
FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Open fuel filler lid.
4. Open fuel filler cap and release the pressure inside fuel tank.
5. Lift to hold rear seat cushion up. Refer to SE-31, "
REAR SEAT" .

6. Remove inspection hole cover for main and sub fuel level sen-
sor units by turning clips clockwise by 90 degrees.
7. Disconnect harness connector and fuel feed hose.

Disconnect quick connector as follows:
–Hold the sides of connector, push in tabs and pull out tube.
–If connector and tube are stuck together, push and pull sev-
eral times until they start to move. Then disconnect them by
pulling.
