Have you had the fuel line disconnected to see the hole? The o-rings could have shrank or cracked and started a leak. If the steel has a hole in it, you may be better off trying to yank the whole line from a junked intrepid.
I've never liked the idea of clamping rubber hose on a smooth high pressure line. Its okay temporary to get you home or something. If you do, I'd keep checking it often to make sure its still tight. I'm not sure how much luck you'd have trying to flare the line if its rusting. I'd also use closed clamps like these which are meant for FI.
