32vickey: you are correct. Thats how they are installed. My thoughts on the difference between double flare and AN fittings is, Detroit has been using double flares for ever and if it has been good enough all these years its good enough for me. That being said, the AN fittings are stonger if installed properly, and the only way I would go if I was using Stainless lines. I would take the ones that are leaking and cut them off and reflare....Good luck.....GlennK
