Continual slow leak in power steering hose.
Noticed oil leak on deck last year, put in ps stop leak, and 2 mths ago leak returned. Had problem diagnosed via dye in reservoir & confirmed pressure/supply hoses are leaking. Also informed possible reservoir tank leak, cause low pressure return hoses rarely need replacing!
