2003 wrangler. I was driving down the road when I hear an air leak. I looked under and saw an snapped air line. I called a 4wd off-road parts and explained what it looked like because they installed my lift just days before. They told me it was fine to drive but to bring it in in a few days. The line is pushing air and wraps around the fuel tank and I cannot find the purpose for the line nor the coupler online.
