FUEL FILTER
Air Bleeding
EBS00BLB
After fuel filter is replaced and after fuel system components are
removed/installed, bleed air from fuel path as follows:
1. Move priming pump up and down to bleed air from fuel path.
2. When air is bled, pumping of priming pump becomes heavy stop
operation at that time.
3. Crank the engine until it starts. Do not crank the engine for more
than 30 seconds.
4. If the engine does not starts, stop cranking and repeat step 1
above.
5. If the engine does not operate smoothly after it has started, race
it two or three times.
6. If air cannot be bled easily (pumping of priming pump does not become heavy), disconnect feed-side of
hose between fuel filter and electronically controlled fuel injection pump. After that, operate priming pump
and confirm that fuel comes out.
CAUTION:
Prepare a tray to collect fuel. Prevent fuel from adhering to rubber parts, especially the engine mount
insulator.
Draining WaterEBS00BLC
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:
lCoolant in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volum.
lDrained coolant is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mount insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged and
fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer toFL-16, "
Air Bleeding".
5. Start engine.

WA RN ING:
Be sure to read “General Precautions” When working on fuel system. Refer toFL-3, "
General Precau-
tions"
1. Disconnect battery ground cable.
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.
lAs 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 position.
NOTE:
Adjusting fuel level is to prevent fuel from spilling, when fuel level sensor unit is removed.

5. Remove rear seat bottom.
6. Peel off floor carpet, then remove inspection hole cover.
7. Disconnect the harness connector, fuel feed tube and fuel return
tube.
lRemove the quick connector of the fuel tube as follows.
NOTE:
lHold the sides of the connector, push in tubs and pull out the
tube.
lIf the connector and the tube are stuck together, push and pull
several times until they start to move. Then disconnect them by
pulling.
CAUTION:
lThe tube can be removed when the tabs are completely
depressed. Do not twist it more than necessary.
lDo not use any tools to remove the quick connector.
lKeep the resin tube away from heat. Be especially careful
when welding near the tube.
lPrevent acid liquid such as battery electrolyte etc. from get-
ting on the resin tube.
lDo not bend or twist the tube during installation and
removal.
lDo not remove the remaining retainer on tube or fuel level
sensor unit.
lWhen the tube or fuel level sensor unit is replaced, also
replace the retainer with a new one.

lTo keep clean the connecting portion and to avoid damage
and foreign materials, cover them completely with plastic
bags or something similar.
8. Using a lock ring wrench, remove the lock ring.
9. Remove main fuel level sensor unit and sub fuel level sensor
unit.
CAUTION:
lDo not bend the float arm during removal.
lAvoid impacts such as falling when handling components.
Removal of main fuel level sensor unit:
lRaise the fuel level sensor unit, and remove the jet pump.
lLeave the jet pump on the fuel tank with the fuel hose.
lIf necessary, remove the chamber from the bottom of the fuel
tank.
lRemove the chamber by sliding toward the rear of the vehicle.
Removal of sub fuel level sensor unit:
lRaise and release the sub fuel level sensor unit to remove.
lIf 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.
lWhen installing the chamber and jet pump, insert them fully until
a click sound of full stopper engagement is heard (for jet pump
inlet).
lConnect 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 fol-
lowing the steps below.

lVisually confirm that the two retainer tabs are connected to the connector.
lPull the tube and the connector to make sure they are securely connected.
lInstall fuel level sensor unit with mating mark (triangular protrusion) 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.
lInstall the inspection hole cover with the front mark (arrow) fac-
ing front of the vehicle (Both for RH and LH).
INSPECTION AFTER INSTALLATION
lStart the engine and rev it up, and make sure there is no fuel leakage at connections.
