2.2 Replace the Defective Injection Pipe
Replace the defective injection pipe as soon as possible.
Note: You can use the screw-in unions on the ICU fuel leakage pipe to find a
defective injection pipe that leaks (see 8019 − 1 Fuel leakage system,
paragraph 4.3).
As a temporary procedure, do as follows:
1) Disconnect the two electrical connections (8) from the related rail valve (7) on the
injection control unit (3) to isolate the defective injection pipe.
Injection will continue to operate through the remaining injection pipes, but this makes
the injection time longer and releases an alarm Inj. time too long.
2) Stop the engine.
3) Replace defective injection pipe (see 8733
− 1 Fuel Pressure Piping in the
Maintenance Manual).
