- Always wear safety glasses when working with fuel to protect against squirting fuel.
- Disconnect the battery from the on-board power supply before open the high pressure fuel system.
- Extremely high pressure is present at the high pressure system connections. Before opening or carrying out any operation on the high pressure system, ensure that the lines are not pressurized - risk of injury!
- Lines must not be opened or released when the engine is running - risk of injury!
- When installing used or new high pressure system components, existing seals must be replaced with new ones (for example injectors).
- All fuel lines must be tightened to the specified torque.
- Always check for leaks after opening the high-pressure system - visual inspection.
