Power steering box thread issue

[Nellysheroes]

Hi all,

So I've gone down the power steering route, using Captain Fabs stuff. It's all going very well so far, and I went to fit the hoses. But at the steering box end, the hoses don't seat at all? With the nuts tightened down, the pipe moves up and down a couple of mm. Am I missing something at all?
It looks like the threads in the box don't go down far enough, and that's the problem. Or is it something else?

I've attached a couple of pictures
