Email this guy and he'll sell you some 1/2 air brake line that will work really well. Also, I do not suggest going w/ a kit from ebay. I went w/ a ViAir 480c Compressor, all 1/2" air line, and a 3 gallon tank along w/ the horns mentioned above. I also suggest going w/ a differnet solenoid to allow better airflow. Good Luck.
