I have stainless for brake and fuel. I single flared because of the strength and it was NOT necessary. I haven't had a problem.

The fuel lines are sweet as I used brass for the couplers and that made the routing smooth and orderly.

Got all of my lines from InLine tube in Shelby county in Michigan. They even flared one very hard to flare end for me.

Hope this helps.
