I just fixed this half cracked nylon line on this banjo bolt on the IP. I had duct tape on it for a long time and finally got around to fixing it. Heat gun to soften (almost melt) the nylon stub that's still stuck to the barb, then heat both the barb and nylon tube and pushed it onto the barb. Worked out good. What's the function of this line? Something to do with turbo boost?
