>>C<< HIGH-PRESSURE FUEL HOSE INSTALLATION

CAUTION

Be careful not to allow any engine oil to enter the fuel rail.
1. When connecting the high-pressure fuel hose to the fuel rail, 

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

2. While turning the high-pressure fuel 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 high-
pressure fuel hose and then re-insert it into the fuel rail and 
check again.
