CAUTION / NOTICE / HINT
Note
When replacing an injector (including interchanging injectors between cylinders) or common rail, replace the corresponding injection pipes with new ones.
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 Click here.
