If your looking for tubing to make Tube and Worm rigs Terminal Tackle has bulk tube material but IMO it's junk.
I use plastic tubing from SNL Corp. (a commercial fishing supply dealer) which IMO is excellent and not expensive, I Don't remember the address right off the top of my head but you can find it on line. The tubing is fairly thick walled like most latex tubing I've seen, but unlike latex, if you tie it in a loose overhand knot when not in use it will develop a nice shape to it and will give you great action in the water. It's 7/16 O.D. though, don't know what the I.D. is.
I haven't found any suitable tubing in pink. What I did was buy white tubing and then use Rit dye to get the color I wanted, it works well. Try fuscia, get the water real hot, and don't leave it in too long
