WARNING:
Read “General Precautions” when working on the fuel system. Refer to FL-2, "
General Precaution".
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Check the fuel level with the vehicle on a level surface. If the fuel gauge indicates more than the level as shown (1/2 full), drain
the fuel from the fuel tank until the fuel gauge indicates a level at
or below as shown (1/2 full).
• In case the fuel pump does not operate, use the following pro-cedure.
a. Disconnect the fuel filler hose from the fuel filler tube.
b. Insert fuel tubing of less than 20 mm (0.79 in) diameter into the fuel filler tube through the fuel f iller opening to drain fuel from the
fuel filler tube.
• As a guide, if the fuel tank is full the fuel level reaches or is less than the level on the fuel gauge as shown, when approxi-
mately 20-1/2 (5-3/8 US gal, 4-1/2 Imp gal) of fuel is drained from a full fuel tank.
2. Release the fuel pressure from the fuel lines. Refer to EC-137, "
Work Procedure".

3. Open fuel filler lid.
4. Open fuel filler cap and release
the pressure inside fuel tank.
5. Remove the rear seat cushion. Refer to SE-26, "
SEAT CUSHION : Removal and Installation".
6. Remove the inspection hole cover. NOTE:
Inspection hole cover is held by an adhesive.
7. Disconnect the harness connector (B), fuel feed tube (C) and
EVAP tube (A).
Remove the quick connector as follows:
• Hold the sides of the connector, push in tabs (B) and pull (A) out the tube.
• If the connector and the tube are stuck together, push and pull several times until they start to move. Then disconnect them
by pulling.
CAUTION:
• Quick connector (1) can be disconnected when the tabs (F) are depressed completely. Do not twist it more than
necessary.
• Do not use any tools to disconnected quick connector.
• Keep resin tube (C) away from heat. Be especially careful when welding near the resin tube.
• Prevent acid liquid such as battery electrolyte, etc. from getting on resin tube.
• Do not bend or twist resin tube during installation and dis- connection.
• Do not remove the remaining retainer (2) on hard tube (or the equivalent) (A) except when resin tube or retainer is
replaced.
• When resin tube or hard tube (or the equivalent) is replaced, also replace retainer with new one.

9. Remove nut (A) and remove center floor insulators.
10. Disconnect the rear park brake cable brackets (LH). Refer to PB-6, "
Exploded View".
11. Disconnect fuel filler hose (2) at fuel filler tube (1) side.
12. Disconnect vent hose (3) from fuel tank side.
13. Disconnect EVAP vent line. Refer to FL-14, "
Exploded View".
14. Support the center part of fuel tank (1) using a suitable jack (A).
15. Remove fuel tank mounting bands (LH/RH).
16. Lower suitable jack carefully to remove fuel tank while holding it by hand. CAUTION:
Fuel tank may be in an unstable condition because of the shape of fuel tank bottom. Be sure to
hold fuel tank securely.

17. If replacing the fuel tank, remove the fuel level sensor unit, fuel filter and fuel pump assembly to transfer to
the new fuel tank.
CAUTION:
Do not reuse O-ring.
INSTALLATION
Installation is in the reverse order of removal.
Fuel Filler Hose
• Insert fuel filler hose to the length below.
• Be sure hose clamp is not placed on swelled area of fuel filler tube.
• Install fuel filler hose to fuel t ank, paying attention to install mark.
EVAP Hose
1. Check connections for damage or foreign material.
2. Align the matching side connection part with the center of shaft, and insert connector straight until a "click"
sound is heard.
