Take a ordinary paper clip wrap it around the brass pipe snip off and solder it too the pipe, push on your tygon and zip tie behind the wire barb you have just formed, just make sure you don't have any sharp edges that could cut the tygon, and don't forgett to do the feed inside the tank and outside.

This system works well for me too, but thanks to Pat Roy I now use a tie before and after my home made wire barbs.
