Russel hard tube to AN adapter Question

I have a fuel tank that I bought off of a member here. It has a Russel Hard Tube to AN adapter on the return line. It uses a ferrule to create a seal. Once the fitting is disassembled, can it just be put back together using the same ferrule, or do I have to figure out how to remove the whole thing ferrule and all and replace it?

as long as the ferrule dosen't become sloppy on the line should be fine
