Re: Vacuum Lines, Windshield Wipers

Ok, I finally found some good images of the fuel mounted vacuum pump. This is off of a 1955 Nash Ambassador.
You can see the vacuum line from the manifold that goes to the vacuum pump, then that goes back up directly to the wipers.
The Nash manual also specifies a test for the vacuum pump. Assuming the wipers have good performance when the system is typically operated, then disconnecting the manifold vacuum line from the pump, such that it draws directly from the air, should still slowly operate the wipers.
