The pressurized tube responsible for transporting liquid fuel from the fuel pump to the fuel rail or carburetor. It must withstand high pressures and chemical degradation. A compromised feedline will cause a drop in fuel pressure, leading to lean running conditions, stalling, or a catastrophic engine bay fire.
