I used a 4" nylon 20lb fishing leader. Just cut the swivels off the ends, slip on the fuel tubing and body clips to each loop and your done. They're just a tad long, but when you pull them off, you have plenty to grab. To take off, grab in the middle, twist your wrist and one pin comes out, then pull the other side out. And this way, both clips are on one piece which also makes it harder to lose.
