Bulletin No.: 06-06-04-006

INFORMATION
Subject:
Elimination of Fuel Filler Tube Flapper Door
Models:
2006 GM Passenger Cars and Light Duty Trucks
2006 HUMMER H2, H3
2006 Saab 9-7X
Attention:
The flapper door located in the fuel filler neck has been eliminated on the current Buick LaCrosse (Buick Allure, Canada Only) in production. This
change will be progressively rolled into the other GM products listed above. Do Not attempt to change the fuel filler tube because the flapper is not
present.
New Metal Fuel Filler Tubes Without a Flapper Door
A revised style of fuel filler tube has changed materials from plastic to metal construction. On plastic fuel filler necks, the metal flapper was included as
a safe discharge point for static electricity. With the metal style of fuel filler tube, the entire neck serves as the static discharge point making the flapper
redundant.
Important:
Do Not attempt to change the fuel filler tube because the flapper is not present. Replacement fuel filler tubes will not be equipped with the flapper.
