Hey hyper, can you examine my pics and see if I did anything wrong?
"It has one but it goes all the way through. If you take a look you can see where I marked it. If the vacuum line isnt properly lined up with that mark, then you get the sides of the holes which wont let any air through. As if I tightened it the way it is in the pic then there will be a "0" reading."
Am I getting the sides of the holes which wont let any air through?
