This is what a double flaring tool and a bender look like.
You can rent them at most auto-parts stores.
Measure how long of a hard line you need and buy one closest to that length.
Make sure its longer than what you need.
The flaring tool should come with directions on how to use it.
Play around with some scrap hard line until you feel comfortable using it.
Then bend your hard line accordingly and flare the ends.
The only way you're going to learn how to do this is to try it.
Its alot easier to do than you think.
