Removal and InstallationNJFE0013CAUTION:
+Do not disassemble the accelerator pedal assembly. Do not remove the sensors and the switches
from the assembly.
+Avoid impact from dropping etc. during handling.
+Be careful to keep the assembly away from water.
+Do not adjust the adjusting screw (painted white) of the accelerator work unit.
+When the connector of the accelerator sensor is disconnected, reconnect the connector, and touch
ªCLEARº in ªOFF ACCEL PO SIGº of the active test using the CONSULT-II. Or, warm up the engine,
then leave it idling for approximately 10 minutes.

damage, chafing and deterioration.
If necessary, repair or replace.

CAUTION:
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.

2. Remove connector from water in fuel filter sensor.
3. Remove fuel filter using a fuel filter wrench (commercial ser-
vice tool).
CAUTION:
Do not spill the fuel during removal. If the fuel is spilt, imme-
diately wipe it off. Be especially careful to prevent the fuel
from adhering to the insulators of the engine mounts.
4. Remove water in fuel filter sensor from fuel filter.

INSTALLATIONNJFE0021S02+Install in the reverse order of removal.
+Replace the O-ring of the fuel level warning sensor with a new
one.
+Tighten the fuel filter so that the sealing face contacts the
packing, then retighten it manually by approximately 2/3 turn.
+After installation, operate the priming pump vertically to per-
form air bleeding.
Refer to FE-22, ªBleeding Fuel Filterº.
Bleeding Fuel FilterNJFE00231. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds.
To start the engine more quickly, crank the engine while pump-
ing the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
+When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.
+If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. 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.
+Start engine and let it idle for at least one minute after
performing air bleeding.

Checking Priming PumpNJFE0024Before checking priming pump, make sure that fuel filter is
filled with fuel.
1. Disconnect fuel return hose.
Place a suitable container beneath hose end.
2. Pump priming pump and check that the fuel overflows from the
hose end. If not, replace priming pump.

fitted)
NJFE00251. Remove the connector from filter and water in fuel filter sen-
sor.
2. Turn the key switch ªONº. Lift the float to ensure that the
warning lamp turns on.

: 3.9 - 5.9 N´m (0.4 - 0.6 kg-m, 35 - 52 in-lb)
Discard the old O-ring and replace it with a new one.
Removal and InstallationNJFE0015WARNING:
When replacing fuel line parts, be sure to observe the following.
+Put a ªCAUTION: FLAMMABLEº sign in workshop.
+Be sure to furnish workshop with a CO
2fire extinguisher.
+Do not smoke while servicing fuel system. Keep open flames and sparks 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.
b) 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.
