If you have an air compressor, you can make a venturi pump (I think
that is what it is called) like HF sells. It is simply a block of
aluminum with a T intersection angle drilled into it. The air from the
compressor blows through the straight drilled holes which creates a
vacuum on the remaining leg. I use mine for air conditioner work and it
will pull 29 lbs of vacuum.

Really? With only 14.7lb possible? Did you mean 29" of mercury? G
