Fuel cell information needed

I'm working with my 66 Dart.
After looking at the gas tank position I've come to the conclusion that I'm going to have to go to a fuel cell in order for my electric fuel pump to be below the tank so fuel can flow to it.
I was wondering what others have done so you can still fill the cell from the original position outside the car. I plan on driving this car on the street on weekends and a few trips of 300+ miles so I dont want to be filling from inside the trunk. I'm hoping this is possible. I would also like to keep the spare tire well but it looks doubtful that I can make something work.
Are you running a cell with a foam liner? Or just the cell itself. What is the safety factor of using a cell?
Look forward to your suggestions.
