>>B<< INTAKE MANIFOLD INSTALLATION
1. Coat the intake manifold mounting studs with engine oil.
2. Tighten the intake manifold mounting nuts by the following
procedure.
.
>>C<< FUEL HIGH-PRESSURE HOSE INSTALLATION
CAUTION
Be careful not to allow any engine oil to enter the fuel rail.
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.
