Manifold vacuum

Manifold vacuum is like the way you suck on a straw to get a drink.

When you suck on a straw, air flows through the straw and into your mouth. Similarly, when your car is running, air flows into the engine through a device called a carburetor.

The carburetor mixes the air with fuel and sends it to the engine to create power to move the car.

But there are also other things happening in the carburetor that help the engine run smoothly. When the engine is running, it creates a suction-like force that pulls air from the carburetor through a little tube called a vacuum line.

This vacuum line connects to a device called a vacuum manifold. This manifold is like a big traffic controller that directs the airflow to different parts of the engine.

For example, one part of the manifold directs the airflow to the brake booster, which helps you stop the car. Another part directs it to the heating and air conditioning system, which helps you stay comfortable.

The manifold vacuum helps the engine run smoothly by controlling the amount of air and fuel that enter the engine. It also helps the other systems in the car work properly, so you can drive safely and comfortably.
