What fuel cell is the most direct replacement for the stock tank as far as size is concerned? I am worried that my rear diffuser will not fit if the tank protrudes to far down. I want to put in a cell and aeromotive instead of just the standard duel fuel pump for my 20B. Though the car will just be shown this year, it will see the track later in life.

Any helpful pointers, pictures, would be great.

ATL? Fuel Safe?
