WA RN ING:
Be sure to read “General Precautions” before working on the fuel system. Refer to FL-4, "
General Pre-
cautions" .
1. Check fuel level with the vehicle on a level surface. If the fuel
gauge indicates more than the level as shown (7/8 full), drain
fuel from the fuel tank until the fuel gauge indicates level as
shown (7/8 full).
NOTE:
Fuel will be spilled when removing fuel pump assembly if fuel
level is above the fuel pump assembly installation surface.
As a guide, fuel level is at the level as shown or below when
approximately 12 (3 1/8 US gal, 2 5/8 Imp gal) of fuel is
drained from a full fuel tank.
In case fuel pump does not operate, perform the following
procedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in diameter into fuel filler tube through fuel filler opening to
drain fuel from fuel filler tube.
b. Disconnect fuel filler hose from fuel filler tube. Refer to FL-9, "
FUEL TANK" .
c. Insert fuel tubing into fuel tank through fuel filler hose to drain fuel from fuel tank.
2. Open fuel door and unscrew the fuel filler cap to release the pressure inside the fuel tank.
3. Release the fuel pressure from the fuel lines. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
4. Remove rear seat bottom. Refer to SE-14, "
REAR SEAT" .
5. Turn the four retainers 90° in a clockwise direction and remove the fuel pump inspection hole cover.

CAUTION:
Do not bend float arm during removal.
Do not allow foreign materials to fall into fuel tank. Use a
lint free cloth when handling components.
Avoid impacts such as dropping when handling compo-
nents.
INSPECTION AFTER REMOVAL
Make sure that the fuel level sensor unit, fuel filter and fuel pump is free from defects and foreign materials.
INSTALLATION
Installation is in the reverse order of removal.
Fuel Level Sensor Unit, Fuel Filter and Fuel Pump Assembly
1. Install O-ring to fuel tank without twisting.
2. Install fuel level sensor unit with aligning mating marks (A) on
fuel tank and fuel level sensor unit as shown.
Turn the lock ring (1) until the lock ring is fully rotated into the
fuel tank lock tabs (A) as shown.
Quick Connector
Connect fuel feed tube quick connector using the following procedure.
1. Check the connection for damage or any foreign materials.
2. Align the connector with the tube, then insert the connector straight into the tube until a “click” sound is
heard.
3. After connecting, make sure that the connection is secure using the following procedure.
Visually confirm that the two retainer tabs are secured to the connector.
