This vacuum supply tube plays a vital role in maintaining the proper functioning of the engine by regulating the vacuum pressure.

Why is the Manifold Vacuum Supply Tube Important?

The manifold vacuum supply tube is responsible for delivering vacuum pressure to various engine components, such as the brake booster, PCV valve, and EGR valve. It ensures that these components receive the necessary vacuum pressure to operate effectively. Without the manifold vacuum supply tube, these components may not function correctly, leading to potential engine performance issues.

How Does the Manifold Vacuum Supply Tube Work?

The DL3Z-9C490-G manifold vacuum supply tube is designed to connect the intake manifold to the vacuum-operated components. It acts as a conduit for the vacuum pressure generated by the engine. The tube is made from durable materials to withstand the high temperatures and pressures within the engine compartment.

Signs of a Faulty Manifold Vacuum Supply Tube

Over time, the manifold vacuum supply tube may develop cracks, leaks, or other forms of damage. When this happens, several symptoms may indicate a faulty tube:

• Engine misfires or rough idling
• Reduced engine performance
• Increased fuel consumption
• Brake pedal feels stiff or unresponsive
• Check Engine Light (CEL) illuminates

If you experience any of these symptoms, it is crucial to have your manifold vacuum supply tube inspected and replaced if necessary.

Replacing the Manifold Vacuum Supply Tube

Replacing the DL3Z-9C490-G manifold vacuum supply tube requires some mechanical knowledge and tools. It is recommended to consult a professional mechanic or refer to the vehicle's service manual for detailed instructions. However, here are the general steps involved:
