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 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.
3. Remove fuel-level warning sensor from fuel filter.

INSTALLATIONNJFE0021S02Install in the reverse order of removal.
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-16, “Bleeding Fuel Filter”.

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.
NOTE:
When air is bled completely, pumping the priming pump sud-
denly becomes heavy.
Stop the operation at that time.
If it is difficult to bleed air by pumping the priming pump (the
priming pump does not become heavy during pumping), dis-
connect the fuel supply hose between the fuel filter and the
injection pump. Then, pump the priming pump up and down,
and make sure that fuel comes out. (Use a pan and be care-
ful not to spill fuel. Keep fuel clear of the engine.) After that,
connect the hose, then bleed air again.

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.
Removal and InstallationNJFE0015WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” 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.
