Are you talking about a real 093 turbo kit or a factory ford turbo system? They are completely different when it comes to the oil feed line. The feed line for the real 093 is a braded stainless line that has flare fitting ends on it, no orings are used for it. However if you're talking about a factory ford turbo system then yes Russ is correct in saying you need the same olives as the fuel lines from the filter head.
Also, some people don't eve bother looking, but you need to clean that pipe out very well if you're going to reuse it. Normally theres no reason not to reuse it, but you need to make sure you clean it out because coked up oil deposites build up along the walls of the pipe. If you don't clean them out, sooner or later they are going to break free and there goes your turbo.
