I just installed a set of PRJ gen 3 rails. I was one of the first to get a set. They are very high quality. Support from PRJ was great. Owner himself called me. They even give you a CD with a 23 page instruction attachment full of color pictures. Like it was said engine fire = bye bye car. I had a few issues with leaks but it was my inexperience not PRJ and they were helpfull. You get what you pay for and why cut corners on fuel lines? Too much of a risk to save a few bucks. I have no regrets on mine.
