      Dumb question - AN to tube adapter fittings

      So, what's the deal with AN to tube adapter fittings? I see they come with a crush sleeve. Do you need to flare the line, or does the crush sleeve hold everything in place? I didn't get any instructions with the parts (making me feel like this should be intuitive somehow). Pic of what I have:

      I'm running 3/8" aluminum hard line for feed and return, but I have -6 AN braided hose for the engine and tank for body/engine flex.



      How tight are you supposed to wrench on these things to get it to seal right?
