[3] COMMON RAIL
Common Rail and Injection Pipes
• Do not loosen the injection pipe when the fuel is under high
pressure (within 5 minutes of stopping the engine).
• Do not remove the pressure limiter (5) and rail pressure
sensor (2) from the common rail (4).
• When removing the common rail (4), do not hold it by the
pressure limiter (5) and rail pressure sensor (2).
1. Remove the injection pipe (1).
2. Remove the overflow pipe (3).
3. Remove the common rail (4).
• Store the injection pipes (1) so it does not get any dust in it.
• Store the common rail (4) so it does not get any dust in it.
(When reassembling)
