Where is the line leaking? If it's leaking where a rubber line is hose clamped on to a steel line, you might be able to just cut off a half in or so of line and reconnect. If you're really lucky you'll find it's just a loose hose clamp, but don't count on that. Also, knowing what model year your Taurus is may help get some solutions to common issues with the year of your car.
