power steering question

[ace of shades]

A newbie again. I have searched all night - threads and google - and I haven't found any answers. I am in the middle of putting an 85 454 into my 68 chevy c10. Before this it was mostly stock (350 instead of the 327) and has the factory power steering. The power steering that I'm using came with the BB. My question is
It has the threaded pressure line (send i'm assuming) on the pump, then it has two push on hoses. My small block has the threaded and one push on. There was a line already pushed on (as seen in pic) but its way to long to go to the power steering box; it would reach all the way to the trany lines if needed. What line do I hook my box to and what do I do with the other post
