Wayne, im just the oposite, blue means air and red means fire(fuel). so my dots are red and blue, not my lines, there just whatever color i have. haha!! and i just plug another piece of tubing into my blue line(vent) and run it to my fuel can im pulling from, that way there is no extra transfer, it goes right back where it comes from and is ready for next fueling! but basicly the same routine.
