Power Steering

I replaced the power steering pump and I have a leak. The leak in on the high pressure line at the nut that goes in to the pump. It has no leaking at the threads, but between the nut and line. I was wondering if I could have left out something that should of came out of the old pump? I installed both Teflon o rings! I cannot get the leak to stop. Fluid is shooting out at the nut but not the thread side of the nut. Hope you can help.
