>>C<< FUEL HIGH-PRESSURE HOSE
INSTALLATION

CAUTION

• Be careful not to allow any engine oil to enter the fuel

rail.

• Be careful not to bend the fuel high-pressure hose as it

is made of plastics.

1. When connecting the fuel high-pressure hose to the fuel rail,

apply a small amount of new engine oil to the O-ring and
then insert the fuel high-pressure hose, being careful not to
damage the O-ring.

2. While turning the fuel high-pressure hose to the left and

right, install it to the fuel rail.

3. Check that the injector turns smoothly. If it does not turn

smoothly, the O-ring may be trapped. Remove the fuel
high-pressure hose and then re-insert it into the fuel rail and
check again.
