 Air lines are run under side padding and behind helmet held in place by special pieces forced down between helmet EPS Styrofoam and inside of helmet shell. Note a 3/16" Y connection to air punp was used instead of a "T" 3/16" connector. |

 I cut 1/2" piece of sheet metal to slip between helmet shell and EPS Styrofoam at back of helmet to hold air line. The sheet metal was 2-1/2" long before I curled an end into circle to hold air line at back of helmet. |
