its repairable...its got allen screws on the filler part.Take the interior 1/4 panel off.

The fuel door opens and closes but feels like the hinge point is worn or broken.. How do you remove it from the car to check it?? If you open it too far it gets out of adjustment and you have to mess with it to get it to close in the proper position. Im not sure if yu have to go thru the wheel well or is there anpther way to remove it . Is this repairable or does the complete door assm have to be replaced.????
