Braided lines and AN fittings ...

Are these just for looks on street cars ? I was considering running from fuel pump to carb - looks great but no real advantages, correct ? I'm assuming they come into play when you want fail-safe parts on a race car ?


They are suppose to be the top of line stuff from my understanding (quality). I've always wanted to use it but just don't know how to measure it to fit the things I need it for. Like -6 .... what the heck is that? If there was some kind of cross reference chart or something maybe I could swing it. Then another question is how does the braided hose seal on the hose etc.?? I didn't want to order what I thought was right from Summit then have to return it because it won't fit. I don't know anyone with hands on experience to show me how to use it or has it on there cars. So I stuck with the old rubber hose and clamps bulls**t! lol
