General Information
An analysis of returned parts has determined that any residual damage to the connector may
result in a voltage drop across the module and can lead to repeat failures. Therefore, GM
Engineering is advising technicians to replace the connector anytime the Fuel Tank
Module/Fuel Pump Module is replaced.

Important: Not all vehicles were built with the Metri-Pack 150 Connector. Refer to the
diagrams for identification of the connectors. This bulletin ONLY applies to vehicles equipped
with the Metri-Pack 150 Connector. If the vehicle is equipped with the GT 280 Connector,
disregard this bulletin.

Notice: Do not insert test equipment probes (DVOM, etc.) into the connector. The diameter of
the test probes will deform most terminals. A deformed terminal will cause a poor connection,
which will result in a system failure. To check the integrity of the new splice, the appropriate
test probe for this terminal is a Gray J 35616-2A. Do not use paper clips or other substitutes to
probe terminals. Using a larger terminal test adapter will damage the terminal.
Important: It is important to use the splice sleeves provided with the connector due to the
exposure to moisture. Refer to Splicing Copper Wire Using Splice Sleeves in SI (SI Document
ID 303648) for proper splicing procedures.
