How do you remove the gas filler tube ?

I want to remove this and re-install it the proper way. Looks like u just remove the 3 screws under the gas cap, remove the rubber seal in the trunk and will it slide out without dumping fuel from the tank? Any tips are appreciated. pm me please.

Hey Paul,
Did a little research:
65-71 filler tubes attach to the inside of the quarter panel.
72-76 filler tubes go through the hole of the quarter panel from the outside.
