From GM TechLink, February 2004:
Two new style fuel line quick connects are in use.
The TI Group Global Quick Connector is used on C/K trucks, S/T trucks, Malibu Sedan, Cadillac XLR and the 2004.5 and 2005 Chevrolet Corvette.
The Legris QC is used on Aztek, Rendezvous, Venture, Montana and Silhouette.
Release
Both Types -- To release the quick connect, push on the retainer using hand pressure only. Do not attempt to remove it. (fig. 21)
A - TI type
B - Legris type
Do not use sharp or pointed objects to put pressure on the connector retainer. Using a tool may fracture the retainer, making it less effective at keeping the connector assembled. Also, attempts to remove the retainer with the line inserted will result in retainer breakage.
TIP: If the connector does not release with hand pressure, thoroughly clean it and blow out grit and dirt with compressed air.
Repair
TI Group Global -- If the retainer is broken, it is not necessary to replace the entire fuel line and attached component to repair it. Three sizes of replacement retainers are available (fig. 22)
| 5/16 po | 21992748 |
| 3/8 po | 22717568 |
| 5/8 p0 | 21992746 |
Legris -- Replacement parts are not available for the retainer.
