And run to Autozone and buy a 10mm flare nut wrench. Makes a world of difference when dealing with rusty lines.
Or if there's a Harbor Freight near by, they have a whole set of flare nut wrenches for < $10 iirc. I have a set and they work great for that kind of work.
Are you sure it's 10mm? It looks bigger than that to me...
