It's definitely worth the money to pick up a flare nut wrench. The flare nut wrench grips around most of the nut. You really really don't want to strip those things out. The only way to replace them is to change out the whole steel line. Make sure you start spraying those suckers with liquid wrench a couple of days in advance too. It makes removal much easier. Good luck
