• If items or work required are not covered by the
engine section, follow the procedures in the applica-
ble sections.
• Always use the support poin t specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in prepar ation for the backward shif t of center of gravity.
• For supporting points fo r lifting and jacking point at rear axle, refer to GI-38, " Garage Jack and
Safety Stand and 2-Pole Lift " .

REMOVAL WARNING:
Be sure to read “General Precautions” be fore working on the fuel system. Refer to FL-4, " General Pre-
caution " .
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 pro- cedure.
a. Insert fuel tubing of less than 25 mm (0.98 in) in di ameter 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 .
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-574, " Fuel Pressure Check " .
4. Remove rear seat bottom. Refer to SE-15 .
5. Turn the four retainers 90 ° in a clockwise direction and remove the fuel pump inspection hole cover.

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.
• ⇐ : Front
• 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 qui ck 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 c onnector straight into the tube until a “click” sound is
heard.
