The Fuel Line is a hose like pipe, that has two ends. One end is attached to the tank, and the other is attached to the engine of the car. This fuel line is used to deliver the fuel from one place to another. These are required to provide the vehicle with the right amount of fuel it needs to run the engine. This is a highly critical task, as the fuel needs to be coming in perfect flow to ensure proper working of the system. The fuel line comes with a rubber tubing that serves as a major artery, that pumps the power throughout the vehicle. This fuel line, is solely responsible to deliver fuel from the tank of the vehicle, to the engine of the vehicle. Even a small pin sized hole can cause major issues in the fuel delivery process, and lead to many problem in the working of the vehicle.
