I know I'm quoting an old post. However just because your cars Bumper to Bumper is over, doesn't mean your Emissions is. Since EVAP is considered Emissions equip. it may be covered.Here's a good picture of the whole assembly from an Amazon page selling a replacement:
I just ordered one. My car is out of warranty, and replacement doesn't look too complicated once you remove the hose that connect the air filter box to the intake manifold. Not worth it to me to pay the dealer $300 to install a $40 part.
Reference the TSB & your manual for Emissions Warranty information.
