The picture you  show is a kink at a flex point. The factory is now placing
a spring around the tubing through that area to keep the radius of flex
large to prevent kinking. I have that plus a Tygon outer tubing to take up
potential kinking before it gets to the Nylaflow. Of course, I do not have
the time in service yet...
