Which type of line requires extreme care to avoid kinking during installation?

Suction lines require extreme care to avoid kinking during installation. This is because kinking can obstruct the flow of fuel, creating a vacuum that may hinder the system's performance. Suction lines are responsible for transporting fuel from the storage tank to the pump, and any restriction in the flow can lead to operational issues such as cavitation or pump damage.

Maintaining a smooth, uninterrupted path for the fuel is essential to ensure efficiency and reliability in fuel delivery systems. The integrity of the suction line is crucial, and any kinks can not only affect performance but can also lead to potential safety hazards if the fuel cannot be moved properly.

While gravity fill and vapor-recovery lines also have their specific installation considerations, the critical nature of the suction line's function in maintaining a balanced pressure system makes kinking a significant concern that requires heightened awareness during installation.
