I don't see why you're looking for a specific brake bleeder application for the X5. Just as long as you get the bleeder in the correct size for your calipers, you should be fine. Most of the time cars are generally only 2-3 different sizes anyways. $7 isn't bad at all for them, but 3ft of clear silicone tubing probably costs .50 and you can still do it yourself.

When I've bled brakes by myself, I simply put the wrench on the nut, the tube on the nipple and make sure that the fluid flows upwards before it drops into a bucket/bottle below. The reason why I have it go up first is so that when I press the pedal, it fills and stays filled w/ fluid going upwards, but everything going downwards just drops into the bucket below. With that uphill flow, I'm guaranteed to not get any air bubbles back into the lines. Just as long as you don't have any solid materials in those speedbleeders they'll work, but if something gets lodged in there, you're screwed. You'd be suprised how sometimes even a little piece of something can still come through the lines, but w/ the tight passage between the checkball in the speedbleeder, things might get trapped and cause you other problems.
