What does AN 10 mean and why is it so popular?

The AN standard comes from Army-Navy, originally developed by the U.S. military for ultra-reliable connections in critical environments. Over time, its proven performance made it a standard in motorsport. The number 10 stands for 5/8”, making it ideal for high-flow fuel, oil, or coolant lines in performance builds.
