I don't know about the black drip water line but you can easily get the clear nylon line at hd or lowes fairly cheap and that is what I use without issue

I am not 100% sure but I think the drip tubing is called drip cause it has micro holes through out it to make the water drip through it while under pressure

the clear stuff is found in the regular plumbing isle near where the john guest (quick connect) fittings are located
