There are companies that make them. They are not cheap. See this:
The problem with what you're saying jnorth85 is that perhaps your setup is different or maybe I misunderstand, but my rack doesn't have a flare fitting. Instead it relies on a oring to seal on a flat surface inside of the fitting. I can verify this by looking on the inside the factory lines which don't have a flare fitting on them.
Here is a picture of the high pressure side on the factory line (sorry for the bad picture, cellphones are poor for shots like these):
Here is a picture of the low pressure side on the factory line:
Essentially they are both the same but with different diameters. No flare there. Now look at the rack side fittings:
See the oring seal? No AN flare fittings on this one. At least on the 06 WRX rack I have.
The only modification I would do on these fittings from EARLS is to cut a slight chamfer on the inner diameter of the fitting to resemble the stock fitting and be a bit easier on the oring. That's my plan. But the lines are certainly not a reverse female flare fitting.
