Removal Procedure

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: When replacing the evaporative emission (EVAP) pipe, always replace the pipe with original equipment or parts that meet the GM specifications for this part. The replacement pipe must have the same type of fittings as the original pipe in order to ensure the integrity of the connection.
