ENGINE FUEL (C24SE) 6C-3


W hen working on the fuel system, there are several things to
keep in mind:
•
Any time the fuel system is being worked on, disconnect the
negative battery cable except for those tests where batter
y
voltage is required.
•
Always keep a dry chemical (Class B) fire extinguisher near
the work area.
• Replace all pipes with the same pipe and fittings that were
removed.
• Clean and inspect "O" rings. Replace if required.
•
Always relieve the line pressure before servicing any fuel
system components.
• Do not attempt repairs on the fuel system until you have
read the instructions and checked the pictures relating to
that repair.
• Adhere to all Notices and Cautions.
All gasoline engines are designed to use only unleaded
gasoline. Unleaded gasoline must be used for proper emission
control system operation.
Its use will also minimize spark plug fouling and extend engine
oil life. Using leaded gasoline can damage the emission control
system and could result in loss of emission warranty coverage.
All cars are equipped with an Evaporative Emission Control
System. The purpose of the system is to minimize the escape
of fuel vapors to the atmosphere.



Service Precaution
CAUTION:
Always use the correct fastener in the proper location.
When you replace a fastener, use ONLY the exact part
number for that application. ISUZU will call out those
fasteners that require a replacement after removal. ISUZU
will also call out the fasteners that require thread lockers
or thread sealant. UNLESS OTHERWISE SPECIFIED, do
not use supplemental coatings (Paints, greases, or othe
r
corrosion inhibitors) on threaded fasteners or fastene
r
joint interfaces. Generally, such coatings adversely affect
the fastener torque and the joint clamping force, and may
damage the fastener. When you install fasteners, use the
correct tightening sequence and specifications. Following
these instructions can help you avoid damage to parts
and systems.

Fuel Filter and Associated Parts






Removal
CAUTION: When repair to the fuel system has been
completed, start engine and check the fuel system fo
r
loose connections or leakage. For the fuel system
diagnosis, see Section "Driveability and Emissions".

(2.4L)
1. Disconnect battery ground cable.
2. Disconnect the quick connector from the fuel filter.
3. Pull off fuel filter from the holder to side member side.
4. Remove the fuel filter.

Fuel Filter
Inspection
1. Replace the fuel filter if the fuel leaks from fuel filter
body or if the fuel filter body itself is damaged.
2. Replace the filter if it is clogged with dirt o
r
sediment.
Installation
1. Install the filter to holder from fuel tank front side.
NOTE: Attend direction of fuel filter. (1) to engine side
(2) to fuel tank side.
NOTE: Verify to hang holder hook to fuel filter.






RTW 36CSH000301
2. Connect the quick connector from the fuel tube to
the fuel filter.
NOTE: Pull of the left checker into the fuel pipe.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs.
3. Tighten fuel filler cap until at least one click are heard.
4. Connect the battery ground cable.
Inspection
After installation, start engine and check for fuel
leakage.
In–Tank Fuel Filter
The filter is located on the lower end of fuel pickup tube
in the fuel tank. It prevents dirt from entering the fuel
pipe and also stops water unless the filter is completel
y
submerged in the water. It is a selfcleaning type, not
requiring scheduled maintenance. Excess water and
sediment in the tank restricts fuel supply to the engine,
resulting in engine stoppage. In such a case, the tank
must be cleaned thoroughly.

Fuel Tube / Quick – Connector Fittings
Precautions
• Do not light a match or create a flame.
• Keep flames away from your work area to prevent
flammable materials from catching fire.
• Disconnect battery ground cable to prevent
electrical shorts.
• Pre-treat piping system or associated parts from
thermal damage or from spattering when welding
or similar heat-generating work.
Cautions During Work

(2) Port
(3) Connector
(4) Plastic Tube

Do not expose the assembly to battery electrolyte or do
not wipe the assembly with a cloth used to wipe off spilt
battery electorolyte.
Piping that has been splattered with battery electrolyte
or battery electrolyte soaked cloth that was wiped on the
piping cannot be used.
Removal
1. Open the fuel cap to relieve the fuel pressure in the
tank.
Use compressed air to remove any dirt on the fuel
quick connect fittings prior to disconnecting the
fittings.





141R100002
W hen disconnecting the fuel pipe, cover the area
with a cloth to prevent fuel from splashing as the
fuel pipe may still have some pressure in it.
2. For removal of the quick connector, hold the quick
connector in one hand, and pull out the connento
r
with the other hand while pressing the square
relieve button of the connector, as illustrated.






140R100037
NOTE: Do not use tools of any kind. Only use bare
hands when disconnecting the connector. Use a
lubricant (light oil) and/or push and pull the connecto
r
until the pipe is disconnected.
Cover the connectors that was removed with a
plastic bag, to prevent dust or rain water from
entering.

Reuse of Quick–Connector
• Replace the port and connector if scratch, dent or
crack is found.
• Remove any dirt build up on the port when installing the connector. Replace the connector, if there is an
y
forms of rust, dent, scratch.
•
After cleaning the port, insert it straight into the
connector until it clicks. After it clicks, try pulling at
49N (5kgf) it out to make sure that it is not drawn
and is securely locked.

Assembling Advice
By applying engine oil or light oil to the pipe, port makes
pipe assembly easier. The pipe assembly should take
place immediately after applying oil (to prevent dust
from sticking to the pipe surface – which ma
y
decrease sealing ability).
Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the “ON" position and listen
for pump start-up sound. Inspect for leaks, the
fuel pressure will increase as the fuel pump is
actuated.
3. Perform leak inspection (step 2) several times.
4. Start the engine and observe the engine idle speed.
The presence of dirt in the fuel system may affect
the fuel injection system.
