If its not in the place indicated by the Haynes Manual, look for any tube that has a restriction, or kink, or smaller area to it. Its done so the tube cannot move from its position when inserted. In some vehicles you need to buy the entire line since it cannot be removed. If there is no split in the line near where it is located then you probably need to buy the entire line. I would have to go look at my car to say for sure. BTW if it is removable, there is a special tool for removing it so you don't break it. Maybe you can borrow or rent it from your local auto parts.
