Should be conical seal faces so I'm not sure where those gaskets would go.
Make sure the tube and filter mating surfaces are clean and in good shape, put a drop of oil/grease on the back side of the flares where the nut will press against it and lightly snug it up to make sure the faces are all aligned properly (give it a little twist as you snug it up) and it should be good to go. if the line faces are screwed you can touch them up or get some conical washers (copper)
