Just a random thought, could you have inadvertently installed a check valve (or two) backwards?
That's something I could see myself acomplishing.
It could account for your symptoms of no vacuum after a rebuild of a previously working vacuum pump.
Do you know if the pump ever produced vacuum before you rebuilt it?
