I filled the resevoir to just see if it would work. It did even though it has been ran dry for 3 years. The only thing is that it leaks out the hoses, which need replaced but it is making a loud noise when I turn it either way. Do you think its the rack or the pump making the noise? Its hard to tell even laying under there with someone turning the wheel.....I would say the pump, would the rack even make a noise???
