Unhappy 2001 Ford F150 6cyl. Manual

I have what appears to smell and look like a coolant leak. I have a metal tube that appears to be a double flare joint on a metal tube on top of the engine at the front leaking. The tube ties into the top of the engine in three places on each side. Is this a fuel rail?

A picture would be helpful, but it sounds like the pipe you are referring to is part of the A.I.R. (Air Injection Reaction) system, if it were leaking you would hear an exhaust leak. As for the coolant leak, have it pressure tested to find it.
