On the power steering gear box there is a tube that goes from front to rear, guess it recirculates power steering fluid. I have found it in drawings but it never has a part number. When I went to the auto parts store the computer only lists the other 3 hoses associated with the power steering system.

The tube on top is what I am referring to.

 

If you can get the line off a local shop should be able to match it with a piece of similar hard brake line, maybe re-use your ends and then just have the ends flared.
