well, the darn thing is out

makes sense
will plumb it to have positive pressure (air cleaner) on one side and "ex" vacuum on the other...
cool went out the the A1 and fired it up, the fuel pump vacuum is quite strong, and the pcv valve vacuum comes to a "T" a few inches away from the distributor, this thing has a npt plug on one end, took it out and there is quite a bit of vacuum, quite strong, could easily go from that point to the distributor just inches away. the air cleaner has two ports on it for air, will use one and go to the other side of distributor, should be a good flow of clean cool air coming in and going out the other side to vacuum. probably put a npt plug into the unused port on air cleaner. I have the air cleaner intake pulling the fumes from the crankcase thru the oil fill, but it is only fumes and not any pressure so it should be inconsequential on the plan
