As an automotive expert with years of experience in the field, I can tell you that the vacuum line in a car is a critical component that plays a significant role in the operation of various systems within the vehicle. It is also known as a vacuum hose or vacuum tube, and it is a flexible rubber connection that routes manifold vacuum to various components and accessories. The vacuum line is an integral part of the engine's vacuum system, which utilizes the vacuum created by the engine's operation to power or assist in the functioning of several vehicle systems.
The manifold vacuum, which is the vacuum pressure difference between the intake manifold and the atmosphere, is harnessed by the vacuum line to perform several tasks. Here are some of the primary functions of the vacuum line:
1. Brake Booster: One of the most critical uses of the vacuum line is in the power brake system. The vacuum from the engine is used to assist the driver's force on the brake pedal, thereby increasing the braking power and making it easier to stop the vehicle.
2. EGR System: The Exhaust Gas Recirculation (EGR) system uses vacuum to control the flow of exhaust gases back into the engine. This helps to reduce emissions by lowering the combustion temperature.
3. Fuel System: In some vehicles, the vacuum line is used to control the fuel pressure regulator, which helps maintain the correct fuel pressure in the fuel system.
4. Climate Control: The vacuum line can be used to control the operation of the heating, ventilation, and air conditioning (HVAC) system, particularly in older vehicles where vacuum-operated controls are used for air flow and temperature adjustments.
5. Windshield Wipers: In some older models, the vacuum line can power the windshield wiper motor, although this is less common in modern vehicles with electric wiper motors.
6. Idle Control: The vacuum line can also be used to control the idle speed of the engine, ensuring that it runs smoothly at low speeds.
7.
Evaporative Emission Control: The system that controls the evaporative emissions from the fuel tank often uses vacuum to operate the various valves and components.
8.
Transmission Control: In some automatic transmission systems, vacuum is used to control the operation of the transmission, including gear shifting.
The vacuum line is designed to be flexible to accommodate the movement of the vehicle and to ensure a reliable connection between the engine and the various components it serves. It is made from materials that can withstand the heat and the vacuum pressure it carries.
It's important to regularly inspect and maintain the vacuum lines in your vehicle. Over time, these hoses can become brittle, crack, or become disconnected, which can lead to a variety of issues, from poor brake performance to engine misfires. A faulty vacuum line can also cause the check engine light to come on, indicating a problem with the vacuum system.
In summary, the vacuum line is a vital component in a car's engine management and auxiliary systems, providing the necessary vacuum pressure to assist in the operation of critical vehicle functions. Ensuring that the vacuum lines are in good condition is essential for the safe and efficient operation of your vehicle.

A vacuum hose, which can also be referred to as a --line-- or a --tube,-- is a flexible rubber connection that routes manifold vacuum to various components and accessories. Since vacuum can be used to power everything from a vacuum brake booster to a windshield wiper motor, a vehicle may contain dozens of these hoses.Oct 22, 2013
