I have converted all brake and fuel lines, hard and soft over to AN fittings, steel braid, and stainless hardline. It solved a couple issues for me;
1. I need only one type of pressure fitting everywhere in the car;
- Brakes
- Fuel
- AC
- Power Steering
2. AN fittings are supplied by several vendors and available at most speed
shops
3. Flex lines and hardlines are now generic or you can custom build yourself
4. I shop for many of my brake line parts at the following:

And Earls/Aeroquip/others for stainless fittings.
