Manifold Vacuum
For your info, I just finished connecting a vacuum gauge to the windshield wiper fitting on the firewall of my Victoria. Idling at 160F, the gauge reads 22 InHG which is an excellent reading. The engine is a Model B with a 6:1 compression cylinder head, stock Model B camshaft and a Model A Zenith 2 carburetor. This engine has approximately 2500 miles on it since it was completely rebuilt. The vacuum gauge is a 2" diameter unit made by Auto Gage and it will stay in the car.
I do not use the stock windshield wiper, and this year the stock wiper motor will be replaced by an electric unit.
