Fuel pump access panel?

I just read the post with the guy asking about an inertia switch on his GM vehicle and he was told that it did not have one and was also told that no GM vehicles had an access panel for the fuel pump. My car listed above does have an access panel inside the vehicle behind the back seat that is accessible in the trunk. I just replaced the fuel tank pressure sensor (on top of the fuel pump) and the access panel is the way I did it. Thanks for letting me put my two cents in.
