FUEL SYSTEM 6C – 9
Removal
CAUTION: When repair to the fuel system has been
completed, start engine and check the fuel system for
loose connection or leakage. For the fuel system
diagnosis, see Section “Driveability and Emission".
1. Disconnect battery ground cable.
2. Loosen slowly the fuel filler cap.
NOTE: Be careful not to spouting out fuel because of change
the pressure in the fuel tank.
NOTE: Cover opening of the filler neck to prevent any dust
entering.
3. Jack up the vehicle.
4. Support underneath of the fuel tank with a lifter.
5. Remove the inner liner of the wheel house at rear left side.
6. Remove fixing bolt of the filler neck from the body.
7. Disconnect the quick connector (3) of the fuel tube from the
fuel pipe.
NOTE: Cover the quick connector to prevent any dust entering
and fuel leakage.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in this
section when performing any repairs.
8. Remove fixing bolt (1) of the tank band and remove the tank band (2).
9. Disconnect the pump and sender connector on the fuel
pump and remove the harness from weld clip on the fuel
tank.
10. Lower the fuel tank (5).
NOTE: W hen lower the fuel tank from the vehicle, don’t scratch
each hose and tube by around other parts.













Installation
1. Raise the fuel tank.
NOTE: W hen raise the fuel tank to the vehicle, don’t scratch
each hose and tube by around other parts.
2. Connect the pump and sender connector to the fuel pump and install the harness to weld clip on the tank.
NOTE: The connector must be certainly connected against
stopper.
3. Install the tank band and fasten bolt.
Torque N·m (kg·m / lb ft)
68 (6.9 / 50)

Service Precautions
Matters that require attention in terms of
maintenance
To prevent damage to the engine and ensure reliabilit
y
of its performance, pay attention to the following in
maintaining the engine:
• W hen lifting up or supporting the engine, do not
apply a jack on the oil pan.
W hen taking down the engine on the ground, do not make the bearing surface of the oil pan touch
the ground directly. Use a wooden frame, fo
r
example, to support the engine with the engine
foot and the flywheel housing.
Because there is only a small clearance between the oil pan and the oil pump strainer, it can
damage the oil pan and the oil strainer.
• W hen the air duct or air cleaner is removed, cove
r
the air intake opening to prevent foreign matter
from getting into the cylinder. If it gets
contaminated, it can considerably damage the
cylinder and others while the engine is operating.
• W hen maintaining the engine, never fail to remove
the battery earth cable. If not, it may damage the
wire harness or electrical parts. If you need
electricity on for the purpose of inspection, fo
r
instance, watch out for short circuits and others.
•
Apply engine oil to the sliding contact surfaces of
the engine before reassembling it. This ensures
adequate lubrication when the engine is first
started.
• W hen valve train parts, pistons, piston rings,
connecting rods, connecting rod bearings o
r
crankshaft journal bearings are removed, put them
in order and keep them.
• W hen installing them, put them back in the same
location they were removed from.
• Gaskets, oil seals, O-rings, etc. must be replaced
with new ones when the engine is reassembled.
•
As for parts where a liquid gasket is used, remove
an old liquid gasket completely and clean it up
thoroughly so that no oil, water or dust is clinging
to them. Then, apply the designated liquid gasket
to each place anew before assembly.

• Surfaces covered with liquid gasket must be
assembled within 5 minutes of gasket application.
If more than 5 minutes has elapsed, remove the
existing liquid gasket and apply a new liquid
gasket.
• W hen assembling or installing parts, fasten them
with the prescribed tightening torque so that the
y
are installed properly.

Matters that require attention in specifically dealing
with this engine.
Holes or clearances in the fuel system, which serve as
a passage of fuel, including the inside of the injector,
are made with extreme precision. For this reason, the
y
are highly sensitive to foreign matter and, if it gets in, it
can lead to an accident on the road, for instance; thus,
make sure that foreign matter is prevented from getting
in.

W hen servicing the fuel system, every precaution must
be taken to prevent the entry of foreign material into the
system.
• Before beginning the service procedure, wash the
fuel line and the surrounding area.
• Perform the service procedures with clean hands.
Do not wear work gloves.
• Immediately after removing the fuel hose and/o
r
fuel pipe, carefully tape vinyl bags over the
exposed ends of the hose or pipe.
• If parts are to be replaced (fuel hose, fuel pipe,
etc.) do not open the new part packaging until
installation.

Work procedure
• The fuel opening must be quickly sealed when
removing the fuel pipe, injection pipe, fuel injector,
fuel supply pump, and fuel rail.
• The eyebolts and gasket must be stored in a clean
parts box with a lid to prevent adhesion of foreign
matter.
• Fuel leakage could cause fires. Therefore, afte
r
finishing the work, wipe off the fuel that has leaked
out and make sure there is no fuel leakage afte
r
starting the engine.
