on a gas engine I would use a vacuum port on the manifold but a diesel I would use the ac vacuum pump but keep the fluid level low enough so the fluid does not get sucked into the pump. It will sound really loud as you turn the wheel back and forth. If you take the cap off you will see a lot of foam. May have to do it a few times than shut it off and let the foam go away. Never had to replace a pump after just replacing lines.
