Checking Fuel LinesEBS00KOS
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace damaged parts.
General PrecautionsEBS00KOT
WARNING:
when replacing fuel line parts, be sure to observe the following.
●Put a “ CAUTION: INFLAMMABLE” sign in workshop.
●Be sure to work in a well-ventilated area and furnish workshop with a CO2 fire extinguisher.
●Do not smoke while servicing fuel system, keep open flames and spark away from work area.
CAUTION:
●Before removing fuel line parts, carry out the following procedures.
–a) Put drained fuel in an explosion-proof container and put the lid on securely, keep the container
in safe area.
–b) Release fuel pressure from fuel line, Refer to EC-775, "FUEL PRESSURE RELEASE" [QR20DE
(WITH EURO-OBD)], EC-1139, "
FUEL PRESSURE RELEASE" [QR20DE (WITHOUT EURO-OBD)],
EC-42, "
FUEL PRESSURE RELEASE" [QR25DE (WITH EURO-OBD)] or EC-452, "FUEL PRESSURE
RELEASE" [QR25DE (WITHOUT EURO-OBD)].
–c) Disconnect battery ground cable.
●Always replace O-ring and clamps with new ones.
●Do not kink or twist tubes when they are being installed.
●Do not tighten hose clamps excessively to avoid damaging hoses.
Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
●After installing tubes, make sure there is no fuel leakage at
connections in the following steps.
–a) Apply fuel pressure to fuel lines with turning ignition
switch “ON” (with engine stopped). Then check for fuel
leaks at connections.
–b) Start the engine and rev it up and check for fuel leaks at
connections.

REMOVAL
WARNING:
Be sure to read “General Precautions” when working on fuel system. Refer to FL-3, "
General Precau-
tions" .
1. Release fuel pressure from fuel line. Refer to EC-775, "
FUEL
PRESSURE RELEASE" [QR20DE (WITH EURO-OBD)], EC-
11 3 9 , "FUEL PRESSURE RELEASE" [QR20DE (WITHOUT
EURO-OBD)],EC-42, "
FUEL PRESSURE RELEASE"
[QR25DE (WITH EURO-OBD)] or EC-452, "FUEL PRESSURE
RELEASE" [QR25DE (WITHOUT EURO-OBD)].
2. Open fuel filer lid.
3. Open the filler cap and release the pressure inside the fuel tank.
4. Check fuel level on level place. If gauge indicates more than the
level shown in figure (full or almost full), drain fuel from fuel tank
until gauge indicates level shown in figure or below.
In case of fuel pump does not operate, take 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.
c. Insert fuel tube into fuel tank through fuel filler hose to draw fuel
from fuel tank.
●As a guide, fuel level becomes the position shown in figure or
below when approximately 15 liter (13-1/4 lmp qt) of fuel are drained from fuel tank.
NOTE:
Adjusting fuel level is to prevent fuel from spilling, when fuel level sensor unit, fuel filter and fuel pump
assembly is removed.

5. Remove rear seat bottom.
6. Remove inspection hole cover, harness connector and fuel feed hose.
●Disconnect the quick connector as follows.
●Remove the quick connector cap.
●Hold the sides of the connector, push in tubs and pull out the
tube. (The figure is shown for reference only.)
●If the connector and the tubs are stuck together, push and pull
several times until they start to move. Then disconnect them
by pulling.
CAUTION:
●The quick connector can be removed when the tabs are
completely depressed. Do not twist it more than neces-
sary.
●Do not use any tools to remove the quick connector.
●Keep the resin tube away from heat. Be especially careful when welding near the tube.
●Prevent acid liquid such as battery electrolyte etc. from getting on the resin tube.
●Do not bend or twist the tube during installation and disconnection.
●Do not remove the remaining retainer on tube.
●When the tube is replaced, also replace the retainer with a new one.
Retainer color: Green.
●To keep clean the connecting portion and to avoid
damage and foreign materials, cover them completely
with plastic bags or something similar.
7. Using a fuel tank lock ring wrench, remove the lock ring.
8. Remove main fuel level sensor unit, fuel filter, fuel pump assem-
bly and sub fuel level sensor unit.
CAUTION:
●Do not bend the float arm during removal.
●Avoid impacts such as falling when handling compo-
nents.
●Removal of main fuel level sensor unit, fuel filter, fuel pump
assembly.
●Raise the sender unit, and remove the jet pump to remove the
sender unit.
●Leave the jet pump on the fuel tank with the fuel hose.

●If necessary, remove the chamber from the bottom of the fuel tank.
●Remove the chamber by sliding toward the rear of the vehicle.
Removal of sub fuel level sensor unit.
●Raise and release the sub fuel level sensor unit to remove.
●If necessary, remove the jet pump inlet from the bottom of the fuel tank.
To remove it, pinch the tabs (2 places).
INSPECTION AFTER REMOVAL
Make sure the fuel pump strainer is free from foreign materials, If any are found, remove them.
INSTALLATION
Install in the reverse order of removal paying attention to the follow-
ing.
●When installing the chamber and jet pump, insert them fully until
a click sound of full stopper engagement is heard (Ditto for jet
pump inlet).
●Connect the quick connector as follows.
1. Check the connection for damage and foreign materials.
2. Align the connector with the tube, then insert the connector straight into the tube until a click is heard.
3. After connecting, make sure that the connection is secure by following the steps below.
●Visually confirm that the two retainer tabs are connected to the connector.
●Pull the tube and the connector to make sure they are securely connected.
●Install fuel level sensor unit with mating mark (triangular pro-
trusion) facing between two carved lines on fuel tank. (Figure
shows left side of fuel tank.)
NOTE:
On right side of fuel tank, there are three carved lines on fuel
tank. Set mating mark between two outer carved lines.
●Install the inspection hole cover with the front mark (arrow)
facing front of the vehicle (Both for RH and LH).
INSPECTION AFTER INSTALLATION
Make sure there is no fuel leakage at connections in the following steps.
1. Apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then check for fuel
leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections.
