Installation
Warning! The connection of the pressure regulator with the fuel rail and the fuel line tube are sealed with rubber rings. Check the condition of the rings on the new regulator. If they have cracks, breaks or other defects, replace the damaged sealing rings.
After lubricating the sealing ring with a thin layer of engine oil, install the new fuel pressure regulator in the reverse order.
