I have a leak in my power steering hose from the resivoir to the pump. Seems to be a 5/8'' or maybe 9/16" hose. I tried all the local autopart stores without any luck to find a replacement hose (bulk hose) and even tried Nissan. They told me the part was no longer available. There has to be appropriate hose out there somewhere...anybody know where? I tried a 1/2'' transmission cooler hose...just couldn't get it to go on. Thanks for any help.
