Never had to remove the fill pipe from the car. All that you have to do is take the 5 (or so) screws that hold the pipe's rubber seal to the trunk floor. That gives the pipe enough wiggle room to allow easy removal/replacement of the tank.
Wow I really appreciate it , knowing it's not beyond my skill level I still want to do it right and not muck it up, so much appreciate all the feedback! Love this forum! Thanks 69 340 GTS!
