    1950 Buick Special, Wiper Vacuum Hoses

    Im restoring my 50 Buick Special and am hoping you can answer a quick question for me. Im replacing my windshield wiper vacuum hoses and have replaced the rubber running from the pump, to the "tee" just before the nozzle on the passenger side wiper motor. I've also replaced the hose running into the passenger side of the wiper motor. Theres a "nozzle" coming out of the drivers side wiper motor, but my shop manual does not say where this hose connects to. Can you help?

    The pics of my car are on a yahoo buick car club site, but ive posted the links below. Any help you can give would be GREATLY appreciated.

    Unfortunatly Yahoo will not allow people to view the pictures unless they are registered, so at least I can't see them.

    Without looking, remember there has to be a line in to the motor to draw air into.

    If you have a dual diaphragm fuel pump, there should be a hose running from the wiper motor to the upper diaphragm, rear side, then another from the front of the upper diaphragm around to the intake manifold behind the carb. The upper diaphragm on the fuel pump is a vacuum booster.

    Mystery Nozzle of Wiper Motor

    In reference to the nozzle which your shop book fails to state what should be connected to it, Bob's reply is probably right. There should be a nozzle to draw air. Nothing should be connected to it.
