What year and size is your truck?
If a child runs in front of your truck during a parade you'll be glad you have a working hydrovac.
The Hydrovac provides a 35% increase in line pressure, so if 78buckshot uses 100 pounds of leg pressure to stop his truck you'll get the job done with 65 pounds of leg pressure.
NAPA used to carry rebuilt units...and there are companies that rebuild then for you. For me for the ~$300 cost, it's not worth not having it working.
