These are a couple of cutting tools that you couls use to make a new cut in your existing line, then de-burr the inside if you are going to use a rubber hose. You could buy a length of tubing and bend yourself, you would have some waste as you learn, but after a wile it is childs play, up to you if you want to learn. I purchased pre-bent lines for my e-body, I think they were about 90 bucks, I could be wrong.
