Disconnect the rail pressure sensor connector (A).
Common Rail Fuel Injection System is subject to extremely high pressure (Approximately 1,600 bar)
Never perform any work on injection system with engine running or within 30 seconds after the engine stops.
Always pay attention to safety precaution.
Ensure the absolute cleanliness.
It is not recommended to remove the injectors without any notice.
Turn ignition switch to OFF position.
Disconnect the negative battery (-) terminal and wait for about 30 seconds.
Disconnect the rail pressure sensor connector (A).
Disconnect the rail pressure regulator valve connector (B).
Remove the high pressure pipe (C) connecting injectors and the common rail.
Remove the high pressure pipe (D) connecting the high pressure fuel pump and and the common rail.
Remove the intake manifold (Refer to the group "EM" in this WORKSHOP MANUAL).
Unscrew the common rail mounting bolts (A) and the remove the common rail (B).
Install the common rail according to the reverse order of "REMOVAL" procedure.
When installing the high pressure pipe, apply the specified tightening torques to the flange nuts of the injectors, the high pressure pipe, and the common rail side with SST (Refer to below table).
