REMOVAL SERVICE POINTS
.
<<A>> FUEL HIGH-PRESSURE HOSE DISCON-
NECTION
CAUTION
Do not kink the fuel high-pressure hose as it is made of
plastics.
1. Insert a flat-tipped screwdriver [6 mm (0.24 inch) wide and 1
mm (0.04inch) thick] into the retainer of the fuel
high-pressure hose connector.
CAUTION
When pushing up the retainer of the fuel high-pressure
hose connector, pay attention to avoid damage to the
retainer.
2. Turn the flat-tipped screwdriver inserted into the retainer by
90 degrees to push up the retainer and unlock the fuel
high-pressure hose connector.
3. Disconnect the fuel high-pressure hose.

INSTALLATION
CAUTION
When applying the engine oil, make sure not to allow the
engine oil to enter the fuel rail inside.
1. Apply a small amount of new engine oil to the O-ring.
2. Turning the fuel injector assembly to right and left, install it to
the fuel rail with care not to damage the O-ring. After the
installation, check for its smooth rotation. At this time, check
that the projection of the fuel injector assembly is in the
center.
3. If the rotation is not smooth, the O-ring may be caught.
Remove the fuel injector assembly and check the O-ring for
damage. After this, re-insert it to the fuel rail and check for
its smooth rotation.
.
>>D<< FUEL INJECTOR SUPPORT
INSTALLATION
Install the fuel injector support to the fuel injector groove and
fuel rail flange, and fix the fuel injector assembly and fuel rail.
.
>>E<< FUEL RAIL AND FUEL INJECTOR

>>F<< FUEL HIGH-PRESSURE HOSE
CONNECTION
1. Pull up the retainer of fuel high-pressure hose to unlock
before installing.
CAUTION
• When pushing in the retainer of the fuel high-pressure
hose connector, pay attention to avoid damage to the
retainer.
• After the installation of the fuel high-pressure hose,
slightly pull the fuel high-pressure hose to check that it
