Remove the high pressure fuel pipe (C) connecting the common rail with the high pressure fuel pump.
Common Rail Fuel Injection System operates with extremely high pressure (approximately 1,600bar), 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 O-ring 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 regative (-) battery cable.
Disconnect the rail pressure sensor connector (A).
Disconnect the return hose (D) from the common rail.
Remove the high pressure fuel pipe (B) connecting the injectors with the common rail.
Remove the high pressure fuel pipe (C) connecting the common rail with the high pressure fuel pump.
