Attention.
The fuel injection system with a fuel rail operates at very high pressure (approximately 1800 bar). Therefore, it is prohibited to carry out work on the injection system with the engine running and for 30 seconds after the engine has stopped.
It is necessary to keep the system parts and the work area clean.
Pay attention to foreign substances.
The protective cover of the nozzle, tube or hose must be removed immediately before installation.
Do not remove the injector unless necessary.
When installing the injector:
- Wash the contact surface of the injector and replace the washer (gasket) with a new one.
- Apply oil to the injector seal ring.
- To avoid impact damage, insert the injector into the cylinder head vertically.
When installing the high pressure fuel line:
- Reuse of the high pressure fuel line is not permitted.
