Hello....My '51 Ford has vacuum wipers that stop when even a little bit of throttle is applied. Are there any easy solutions or fixes for this? Or just stay home on rainy days? Is an aux. 6V vacuum pump the solution? Does anyone manufacture an electric replacement 6-volt motor? BT

There are a couple of things you can do to increase the efficiency of the vacuum windshield wipers: You can install a dual action mechanical fuel pump in place of the standard pump on the engine, this pump contains a vacuum pump which you plumb into the vacuum hose which runs between the intake manifold and the windshield wiper unit. Or you can install a vacuum reservoir tank to provide vacuum during brief accelerations. You will need to install a one-way vacuum check valve in the line between the intake manifold and the reservoir.

BT...My wipers on the '50 Sedan worked great when I put it to sleep for the winter in 2014 and in the spring they worked very slow. Got to the point of stopping straight up on the windshield and wouldn't return until I turn the wiper switch to the "off" position. I squirted a couple shots of Marvel Mystery oil into the vacuum line from the carb to the wiper motor and now they work great! I guess the "flapper" got a little brittle. Pat

You can try these things and if it doesn't improve the wiper response, send your motor to: Kent Jaquith, 2633 SW Obsidian # 15, Redmond, Oregon (541) 923-4319 Lubricate the linkage with motor oil. Lubricate the motor by letting the motor suck oil into it and then drive the car with the wipers turned on but without the blades, to distribute the oil and exercise the motor. Put the blades on when it rains or the motor is working good. Repeat this every Spring.

Tom O, You said: "Lubricate the motor (vacuum motor?) by letting the motor suck oil into it". I didn't know that the motor 'sucked'. I always thought that the wiper blade motor was being sucked by the vacuum line attached to it. So how can the lubricating oil be sucked into the vacuum motor? MG

If you disconnect the vacuum hose at the motor and operate the motor by hand, you will notice that in one direction the motor will suck air and in the other direction, it will expel air. I should have mentioned that for this method to to work the motor should be removed, as it will not suck the oil very far.

Hello again...Having performed an extremely scientific inspection of the vacuum system on my '51, I've discovered that it has a single stage fuel pump, and draws it's vacuum from the manifold. So....does anyone have any suggestions as to where I might purchase a quality new double action fuel pump at a reasonable price, and also the method and materials necessary to install it, if any. Thanks to all who posted....BT
