Disconnect the rail pressure sensor connector (A) and rail pressure regulator valve connector (B).
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.
Disconnect the rail pressure sensor connector (A) and rail pressure regulator valve connector (B).
Disconnect the high pressure pipe (C) connecting the injectors with the common rail.
Disconnect the high pressure pipe (D) connecting the common rail with the high pressure fuel pump.
Unscrew the two mounting bolts (E) and remove the common rail (F).
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).
