Rein Automotive OE Quality GDI fuel feed pipes are designed to be direct replacements of the OE high-pressure fuel feed lines used in today's GDI systems. They reside between the high-pressure fuel pump and the fuel rail and are constantly exposed to a very harsh, high-pressure environment; hence, the manufacturer requires replacement of the fuel feed pipes each time the high-pressure side of the system is opened. Rein's OE quality GDI fuel feed pipes ensure that the system is properly sealed and functioning as per the manufacturers' specifications and design. Select the GDI pipe needed for your vehicle.
