Brake pedal goes to floor - Found problem

[SJ]

I found the problem . . . . . Rusted brake line.

I did not notice the leak because it was raining . .the ground was wet, car
was wet, everything was wet. The brake fluid followed the brake line and
exited the car someplace down the line . . I guess it looked like dripping
rain water.

The leaking brake line is the one going from the ABS regulator to the rear
pressure regulator. All  the fittings are corroded. I think I'll cut the
line and and put in a short section of brake line going to the ABS
regulator. This seems the path of least resistance.
I'll buy a section of brake line and a connecting union from my parts guy.
Then all I need to do is cut the line, flare one end and use the union to
connect the two lines.

What kind of flaring tools do I need? Make, brand?
Does FLAPS carry the nipples and connecting parts? Are these standard metric
parts?
Any good sources for the tools?
