Trust me, if it's the low pressure line, the high pressure hose is on it's way out too. I tried to do a band aid fix of the high side line using Gates high pressure power steering hose and several hose clamps. It worked for about 6 miles and then blew as I was pulling into a parking space. What a mess! Anyway, order a full set of Gates or ACDelco hoses, set a weekend aside and replace all the power steering lines at one time.
