I've just converted two vehicles from -10AN (or -8AN) to hard line. In both cases it was for odor in the garage. Both had steel braided rubber line that was about 10 years old.

Unless you use the new materials out there that are supposed to be ethanol safe, or use teflon (PTFE), it will smell in the garage eventually as the modern gasolines seep through the rubber

Unfortunately one of them was on a high-performance truck with two tanks and two pumps and the crazy tank switch w/ return provision was $700! But I digress...
