Removing
1. We prepare the car for operations (see "Vehicle preparation for maintenance and repair").
2. Relieve pressure in the power system (see "Pressure relief in the power system").
3. Disconnect the vacuum hose from the fuel pressure regulator.
4. Key by 24 mm unscrew the union nut that secures the drain tube to the regulator.
5. Hex key by 5 mm unscrew the two screws securing the regulator to the fuel rail and remove it.
An o-ring is installed in the connection between the regulator and the fuel rail.
If, when removing the regulator, the ring remains in the ramp, it must be carefully removed with a screwdriver or tweezers. The connection between the regulator and the tube is also sealed with an o-ring.
Installation
1. Install new o-rings by lubricating them with engine oil.
2. Installation of the pressure regulator is carried out in reverse order.
