There is no button to release fuel pressure.
Fuel door release button/switch.
bmw x5 fuel tank release button
Use emergency release lever in the trunk side to open the fuel door.
On my 1995 it is a button located within the center console armrest. The trunk release button is next to it.
There isn't a fuel door release button on a 2001 or any Porsche Boxster. When the doors to the car are locked the fuel door also locks but when the doors are unlocked the fuel door will unlock. Open the fuel door and lock the doors and you can see how the mechanism works.
No such part on an Avenger.
There should be a fuel door release button on the driver's door, right next to the switches for the power windows and the outside mirror.
If the car is equipped with that option there will be a button in glove box. If no button, then just push inwards on the edge of the fuel door and the rear edge will pop out. If glove box button is present and not working, there will be an emergency release inside the trunk on the back side of the fuel door. Usually a cable or a lever.
There is a button on the dashboard directly under the trunk release. The bottom left button on your remote entry key fob also opens it, and if none of these work, there is a release cable inside your trunk, on the left side {right behind the fuel door}
I was looking at the 2000 Lincoln LS Owner Guide and it states that it is on the INSTRUMENT PANEL , next to the fuel filler door release button ( unfortunately the drawing of the button doesn't show exactly where it is )
