That machine has little use by the looks of it , lucky find . I know for beauty just 1 min up the road from me but they won't sell it and don't use it i have been asking for 25 years now .

w250 1990 cummings the power steering started getting hard to turn pulled the dipstick out to check the oil and there was a pressure buildup and oil started spewing out the reservoir . so i take it the pump is pooched , or could it be the box any other ideas . Thanks .
