I have a 2001 grand prix GT. I am trying to remove fuel pump. I found a video on the interenet that shows a guy removing a fuel pump from another GM car. The problem i am having is that the hole in the trunk that i have seems to be alot smaller than what they guy in video had. After he unscrewed the ring using a screwdriver and a hammer, he simply lifted the whole unit. I have a ring, that turns and locks the fuel pump. The problem is, that ring is WAY too big for the hole in the trunk, and after i take it off, from the fuel tank, there is just no way to take it out. I spend at least an hour trying every single possible way i can come up with. I seen similar 7 screw holes in another video, but the ring on that fuel pump was "C" type, alot smaller.
Is it possible that my car uses wrong ring for the hole size in the trunk? I just can't see how it is possible to take it out. ? I have a feeling the pump was put on the fuel tank,and then fuel tank was attached to the car. Or is there a secret to how it is removed?
