rules on servicing Honda power steering system,
if the high pressure line is leaking, do not use a shop made line, you need to buy a brand new or replacement Honda high pressure line, there is a small damper in the line.
Replace the pump intake pipe if bad and check the reservoir bottle for cracks etc, clean it out completely with kerosene and atf/hydraulic oil assisted with compressed air to remove all debris from the screen in the bottle, Also make sure to blow out the cooler line which is at the front of the car - blow it out backwards to remove any debris from it.
fill system with Honda PSF only or any other PSF which claims to be usable in Honda - using ATF will cause noise in a Honda power steering system as it foams up, Honda PSF will not foam up in the system. Its very stable because of the add packs in the oil. The only problem it suffers from is hard steering effort in really cold weather. So just wait a bit before using it in the winter.
