Fuel FilterEBS0036N
DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump to bleed air.
lWhen air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.
lIf it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.
lStart engine and let it idle for at least one minute after perform-
ing air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
lIt is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at the bottom of the fuel filter.
Accelerator Pedal Released Position LearningEBS009NW
DESCRIPTION
"Accelerator Pedal Released Position Learning" is an operating to learn the fully released position of the
accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed
when accelerator work unit or ECM is replaced.
OPERATION PROCEDURE
1. Turn ignition switch "ON".
2. Select "OFF ACCEL PO SIG" in "ACTIVE TEST" mode with
CONSULT-II
3. Make sure that accelerator pedal is released.

REMOVAL
1. Remove air duct and upper air cleaner case.
2. Remove fuel filter protector.
3. Disconnect fuel hoses at fuel filter bracket.
CAUTION:
Plug the pipe to prevent fuel from draining.
4. Remove fuel filter with bracket.
CAUTION:
Do not splash fuel during removal. If fuel is splashed,
immediately wipe it off.
5. Using band-type filter wrench (commercial service tool), remove
fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Install in reverse order of removal, paying attention to following:
lReplace O-ring on drain plug with new one.
lScrew the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning
approximately 2/3 turn.
lAfter installation, bleed air from fuel path. Refer toFL-16, "Air Bleeding".
INSPECTION AFTER INSTALLATION

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.
