Powersteering tubes au v8

[sgj66]

Hi the steel pipe that comes out of the top of the pump is leaking around where the pressed fittings goes to the nut/bolt not game to mess with it its my only vehicle, how can I find a part number no useful auto supplier out here
It's a 01 xr8 the pipe bends over the pump down has a rubber pipe of maybe a foot long then back to steel then under the air con pump and over to drivers side into the steering rack looks like a pain to change what do I call it or is there a number I can quote
