Common Rail Fuel Injection System operates with extremely high pressure [approximately 1,800 bar (180 MPa / 26,106 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 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.
