On my last trip to Hobby Lobby, I was in their storage area and found little clear cups that screw together to form a 6 cup column. That make sense? Each cup is about 1 1/2" diameter and 1" tall. I think it was $1.99 or $2.99.
I also found bead crimps in sizes 1,2,3,4. I started using the #1 crimp for the ends of fuel lines and the #4 for radiator hose. They're much cheaper than the AN fittings and work fine for my purposes.
