Flaring lines freaking sucks. Chances are that most of the line is fucked and you might get another failure down the road. If you plan on keeping the car for a while I would just go and spend the extra buck and get the pre-formed lines for you car from Acura.

 

I don't know what you guys are talking about, just get a section that is already flared, they sell it in like 6" increments already flared with the metric fittings just bend it like the one you are replacing and screw it in.
