2.
Disconnect the fuel pressure regulator valve connector (A).
Common Rail Fuel Injection System operates with extremely high pressure [approximately 1,600 bar (160 MPa / 23,206 psi)], so never perform any work on injection system with engine running or within 30 seconds after the engine stops.
Keep cleanly the parts and the working area.
Pay attention to a foreign substance.
Just before installing injector, tube or hose, remove the protect-cap attached on them.
Do not remove injector except for special case.
When installing Injector
Wash the contact area of the injector and replace the washer (gasket) with a new one.
Spread oil on the injector O-ring.
To protect damage caused by shock, vertically insert the injector into the cylinder head.
When installing High Pressure Fuel Pipe
Do not use again the used high pressure fuel pipe.
Install the flange nut correctly.
Turn ignition switch OFF and disconnect the negative (-) battery cable.
Disconnect the fuel pressure regulator valve connector (A).
Remove the high pressure fuel pipe (A) connecting the high pressure fuel pump with the common rail.
Disconnect the fuel feed tube quick-connector (B) and the fuel return tube quick-connector (C).
Remove the drive belt (Refer to "TIMING SYSTEM" in "EM" group).
Remove the front cover service plug (A).
