Starting from the Trracer's backbottle ASA adapter, you'll need:
1. An ASA reducer (an adapter with male tank threads on one end and a 3/8" NPT port on the other.)
2. Some kind of hose (macroline will work, I prefer steel braided)
3. A °45 or °90 elbow (needed if you're using a braided steel hose)
4. Some sort of bolt-on bottomline ASA adapter (The Trracer uses standard 3/4" 10-32 AGD/WGP bolts)
