The comment about abrasion reminded me of something.

When you talk with Earl's or anyone familiar with braided steel lines
they may forget to tell you this because everyone knows. The steel
braid will act like a saw on what ever rubs against it.

Say for example you decide to use it as brake line. When it is
installed it will be touching nothing. That may change when you hit a
bump and the wheel travels up. If the braid rubs against a piece of
metal or plastic very quickly it will rub a hole right through it.

As was stated the fittings can be finicky. Some advice is after you
decide what you want to buy go to your local speed shop where you can
buy the hose. Bring your fittings and have them show you how to
assemble them. It is not difficult, the is a proper way to do it.

One other item. Buy the correct tools. If your AN fittings are
aluminum buy the correct aluminum wrench. If you need to flare ends by
the correct flaring tool. If you are going to bend some tubing buy the
correct tubing pliers.

Takes a little practice and after you are done it sure looks good. I
do all of my own fuel and brake lines. My current daily driver is a
'40 Hudson. I bent the tubing for both. The brake lines have AN
fittings and braided steel lines. The fuel lines are standard fuel
hose on barbed fittings.
