Injector lines

I imagine you could bend the tube, as long as the tube is rated for the correct pressure and your bender is capable of doing such a task. The tricky part would be the ends, I don't think you can make these as they are inverted flare. Then there is the task of making sure each line is the same length. For the time invested, and frustration, it may be easier, cheaper, and way quicker to buy a set.
