Trying to hook up a vacuum line to my 61 Galaxie stock vacuum operated wiper motor.. It has two 3/8" ports.Pretty sure it is hooked to the side port but not sure if it is the side or bottom port?
I have no idea but I would think the bottom port would be some type of drain... Ok experts- teach me something new!
On my similar Chevy wiper motor, the side port is for the vacuum source and the bottom port is left open for return air to enter the motor.
