I'm guessing you mean the original or version 2 of the Filstar outlet pipe. This replaces all the old outlet pipe versions that had pieces that clipped together and included a flow control valve. This replaces all that with one simple outlet pipe that fits the original tubing. Attached to that pipe is a simple fan sprayer that swivels in all directions to directs the flow out of the filter.
If you some "c" shaped clips these will work with the new outlet as well. If you have the very old brackets they might not work. The best bet if you have to replace more than a few parts is just to buy all new inlet/outlet accessories. Some of these will be duplicates of what you already have but buying parts individually is usually not cost effective.
