I actually run both air lines into the trunk area. Then I fabbed up a bracket, painted it and run both lines to 2 air pressure gauges my buddy picked me up. It actually worked out really good. I'll have to get some pics. and post them. I run my lines along the brake lines on the axle out of the way of everything and up through the trunk pan. I used rubber electrical grommets thru the trunk pan. I know most people probably won't want to drill 2 small holes in the trunk but I did and it works great.
