just remember that all "AN" fittings use a 37* single flare instead of the 45* double flare used on steel type brake lines.
for "normal" size lines (3/16-3/8) i use a bender i got off the SNAP-ON truck years ago, for "big" lines (1/2, 5/8, 3/4) i made my own dies out of round stock, kinda like a mini JD2 bender die.
for flaring i have a hydraulic flaring tool that i re-cut the cone and seats to 37*
