What is the correct way to vent the blow down tube out of the car. I have my bottle mounted in the back seat and there is a hole in the floor board perfect for venting the tube, but what type of fitting and tubing are supposed to be used for compliance with drag strip safety and nhra.

 

This is what you need. It was put together for what you are doing.
