Too much trouble, and if you get a leak, even more trouble. If the lines are not supported ever 1.5 to 2 feet down their length they will eventually fail from either vibration induced fatigue, or from vibration induced abrasion failure if they are touching and rubbing the inside of the framerail because they are not secured from movement. Thats the second reason the lines are secured to the frame every foot or 2 besides the fact that its an easy way to secure them.
