I have fuel and brake lines from Right Stuff Detailing. Top notch stuff. The fit was excellent on all of them. When I went looking for the new lines, my uncle suggested that I stay away from Fine Lines brake lines. He could never get his to seal, and another local guy couldn't either. He has no experience with their fuel lines. Because I needed both, I went to Right Stuff for one stop shopping. I've been very happy with them, and would definitely use them again.

I went with the 3/8" lines even though I have a 383. So far I've never hooked up the return line. No need to yet.
