old fuel lines and brake lines -Replacement Where and How? Tech tips please!

I would just run what O'Reilly stocks. Do you think they are going to stock unsafe brake line? I've used what we sell a good bit.
That's good logic, but I would bet you money you could find something entirely unsafe that an autoparts store sells.
My store doesn't have allot left - Do I order 3/16" line?

Rob what would you do to build/install fuel line on a daily driver (LA 360 street)?
