Maybe I will use the vacuum pump from my 85 as the vac source and connect the two directly together. If that is not enough, I will look for a compressor from a 120 VAC air conditioner as a source of vacuum.

Nice job on the tester "T", shorter is better when it comes to fitting in the line. I must be missing something, I dont quite get how your testing your VP, what are you using your mity vac (type) for, just the gauge to see what your pumps putting out?
