Info - Replacement of Connector When Replacing Fuel Tank Module/Fuel Pump Module

This bulletin is being revised to provide a technician tip for installing new connector. Please discard Corporate Bulletin Number 04-06-04-088B (Section 06 - Engine/Propulsion System).

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.

Tip
The connector service part number used in this bulletin comes with all white wires. In addition, the connector that comes with the fuel pump assembly has different color wires than the connector currently on the vehicle. Therefore, use the old connector as a wiring map for splicing in new connector.

Notice: Do not insert test equipment probes 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 for proper splicing procedures.
