If you have the option to make a flood coolant system instead of a vacuum, I highly recommend it.
If you do it right, it can costs about the same and you will have better results in terms of health safety with flood coolant vs. vacuum.
Just my .2c
What size micron filters do you use to filter the fiberglass from the coolant?
