CAUTION / NOTICE / HINT
Note
When replacing an injector (including interchanging injectors between cylinders) or common rail, replace the corresponding injection pipes with new ones.
w/ DPF:
When fuel lines are disconnected, air may enter the fuel lines, leading to engine starting trouble. Therefore, perform forced regeneration and bleed the air from the fuel lines.
