The first thing I would do is send the junk CPP booster back. I sent 2 of them back because they leaked and the third one did too, but I just gave up and bought a Tuff Stuff Booster from Summit.

Also, their master cylinders leak also. Not a CPP fan.
The problem you'll soon run into is that when you try and return this leaky booster, ugly customer service will raise it's ugly head.
