On the Rover T-series engines (for the 2004 super-specs), the steering pump is on the same spindle as the water pump. So it is not an option to easily remove it. Therefore I have a looped the input to the output, added a small header tank and filled it with power steering fluid. However, I have used rubber heater hose to attach one end of the pump to my loop. This hose has now swollen to twice its diameter and looks ready to burst. Thus do I need a special hose type to connect this? Would vacuum hose be sufficient? I had previously tried a silicone-rubber hose (which was easy to work with) but did burst. It's hard to imagine that the steering pump is creating pressure to expand this hose, as it's just looped back to the input.
Any ideas gratefully received.
thanks,
