The port for the Injection Actuation Pressure (IAP) sensor has been relocated on the new cylinder head. This new location interferes with the existing tube assembly and a new tube assembly must be used to avoid the sensor in the new location. The new 273-3033 Cylinder Head Gp replaces the existing 214-1979 Cylinder Head Gp within the 214-1980 Cylinder Head Gp .
The new 263-1785 Tube As replaces the existing 221-3463 Tube As on the serial numbers listed above.
Note: The new tube assembly must be installed with the new cylinder head group. The old tube assembly will interfere with the sensor at the new location.
