If you mean fuel pump module. You get to it from the trunk. lift out the carpet, their is an access panel with about 5 8mm bolts, front of trunk, pass side. You have have to crawl all the way into the trunk to get it out. Make sure the hood supports are stable, so you don't lock your self in the trunk !
When your car is in valet mode the trunk cannot be opened with the trunk release button. Your car came with 3 keys, two black ones and a green one. The green one will start the car, and unlock the doors, but it won't open the trunk. That way you can put your Rolex and gold bars in the trunk without having to worry about the valet at the restaurant stealing them.
