What is vacuum hose?
The term vacuum hose can refer to any of the flexible tubes that are used to transmit vacuum power throughout your vehicle. When the hoses get smaller, they tend to be referred to as “vacuum lines” or “vacuum tubing” rather than vacuum hoses, but they essentially work in the same way.
Where does the vacuum line go?
