DETAIL

Should a fuel pump require replacement on a vehicle within the above VIN range, both a replacement pump and an adapter harness will be required. The original style of fuel pump fitted to the vehicle is no longer available as a spare part.

The adapter harness will permit replacement of the older style pump with the newer component.

CAUTION: Two variants of the adapter harness are available because of different vehicle configurations. Ensure that the correct harness is selected for the vehicle under repair.
