"FA INTAKE MANIFOLD

(1)Tighten the nuts on the right bank to 5 - 8 Nm.

(2)Tighten the nuts on the left bank to the specified torque. Then tighten the nuts on right bank to the specified torque.

(3)Tighten the nuts on the left bank and those on the right bank again in that order.

"GAINJECTOR

(1)Apply a small amount of engine oil to the O-ring.

Caution

D Take care to prevent the engine oil from entering the delivery pipe.

(2)Install the injector into the delivery pipe and turn it right and left.

(3)Make sure the injector turns smoothly. If not, the O-ring may be caught. Remove the injector and check for damage to the O-ring, then re-insert it and confirm that it turns smoothly.

(4)When installing the injector, set the delivery pipe setting mark and the injector projecting portion.

"HA FUEL PRESSURE REGULATOR

(1)Apply a small amount of new engine oil to the O-ring, then insert the fuel pressure regulator into the delivery pipe, taking care not to damage the O-ring.

Caution

D Take care to prevent engine oil from entering the delivery pipe.

(2)Make sure the regulator turns smoothly. If not, the O-ring may be caught. Remove the regulator and check for damage to the O-ring, then re-insert it into the delivery pipe and confirm that it turns smoothly.
