Installation is reverse of removal.
When installing the high pressure fuel pipe, apply the specified tightening torques with the special service tool [SST No.: 09314-3A000].
When installing the high pressure fuel pipe connecting the common rail and injector, follow the below procedure.
Temporarily install the nut on common rail.
Temporarily install the nut on injector.
Install the injector side nut.
Install the common rail side nut.
Common rail installation bolts:
19.6 ~ 26.5 N.m (2.0 ~ 2.7 kgf.m, 14.5 ~ 19.5 lb-ft)
High pressure fuel pipe installation nut:
24.5 ~ 28.4 N.m (2.5 ~ 2.9 kgf.m, 18.1 ~ 21.0 lb-ft)
In case of bad start after reinstalling (replacing) the injector, the high pressure fuel pump or common rail, bleed air in high pressure fuel circuit.
After replacing the part, install the others except the injector #5 side high pressure fuel pipe (A).
Install the high pressure fuel pipe (A:31426-3A000) to the injecter #5 side on the common rail, and place the cup (B) at the end of the pipe.
Check to bleed fuel out at the pipe after cranking the engine several times and then, remove the high pressure fuel pipe tightened temporarily.
Install new high pressure fuel pipe (A) to the injecter #5 side with specified torque.
Check the high pressure fuel system for leakage after start the engine.
