Vacuum

[Gamagoat1]

Can someone tell me where the vacuum line for windshield wipers is connected.
Also where the two vacuum vents for the distributer go....
The 715 I'm working on has a non vac. booster fuel pump so must go to the intake manifold or?????? for vacuum.

Thanks

Someone has replaced the fuel pump with a civilian style pump, so you don't have a vacuum pump anymore. That is where the wipers connected to originally. If you connect to the intake manifold, the wipers will slow everytime you accelerate because the vacuum will drop off. You'll probably want an original style pump.

Someone has replaced the fuel pump ...

You'll probably want an original style pump.

Or replace the vacuum wiper motors with electric motors. A. B. Linn had them...

.... or do what I did ..... I also replaced my stock fuel pump with a civi and had my wipers running off the intake manifold. Until ..... I bought an old wagonner vaccum ball of ebay for $11.

here's one now .. but its for a GM.

Great Idea, and easy to hide... Thanks

A vacuum reservoir may help, but you will also need (if it isn't built-in) a check valve.

If you decide to go with electric wipers, just stay away from the Chinese ones. They are junk.

Ther are also some on demand vacuum motors out there. 24 or 12 volt. I think electric wipers are a better option. But there are other ways.

How to avoid chinese junk, who sells the right stuff?
Any motors with 24V?

[randyscycle]

Most of the motors that have the switch made onto the case and are direct drive (no gear box) are made in China these days. The 24V versions I've seen were sold for boats many of which are 24V as well. I am not certain how to tell for sure if they are made in China or not. The problem I had with the cheap Chinese motors is that they don't last more than a few uses. If the windshield isn't soaking wet they barely have enough power to drag the blade across the glass.

I used a set of 12V motors on my truck from Tom's Bronco Parts. They work really well and are gear driven, so they have some power. They may also be made in China, but they certainly look like someone is watching them for the quality control.
