Let's start with the basics. This operation is just that, an operation! Every step is crucial to your success. I have screwed this up in the past and it's super frustrating and this is why I'm going through this now. I know this will save people hours of pain and suffering. Here we have a Toyota line that I used for practice. Notice the shape of the tubing end. It has a bell shape end that has an indent on the inner diameter (I.D.) which presses against the fitting it is inserted into.



The goal is to cut off the tubing and duplicate the factory flare that you see here. So let's get started! Cut off the tube end nice and clean with a regular cutter or even a rotary disc tool or fine saw blade.



No matter what tool you will have to clean up the I.D. I like to use a drill bit and in this case it's mandatory because the tube flare tool die needs to be able to fit inside the tubing. I had to use a slightly larger drill bit and I measured it carefully with the gauge you see in the pictures.
