Power steering hose for 200tdi (RHD) 90

I have burst the high pressure hose from the power steering pump to the box. Upon replacing the part I have found that no trace of the removed part is in any catalogue or manual. I can not even see it on L/rovers Microcat Database. I was wondering if anyone had found the same problem? The hose section on the pump end was split into two sections with a union in the centre as aposed to one hose from the pipe to the pump. Hope this makes sence! I eagerly await your reply!!!
