Dingo,
That tool is for bleeding brakes. That vacuum pump is good at pulling fluid out of stuff. For example, pump up the vacuum and suck out the old fluid out of the brake mastercylinder. Replace that fluid with new, clean stuff. Then break open the bleeder screw (I have speedbleeders on my vehicles) and pump until the fluid rins clear. Same with the Power Steering. Pump out the PS res. and fill with fresh fluid. Turn steering wheel lock to locak. Repeat until fluid looks bright red and smells fresh.
That little pump is too small for the job.
