Attention! Work is carried out on a cold engine.
Disconnect the negative cable from the battery.
Disconnect the fuel pressure regulator vacuum hose from the receiver.
Using a 17 mm wrench, unscrew the drain pipe nut, gradually releasing the pressure. Hold the hose nipple with a wrench of the same size.
The connection between the hose and the tube is sealed with a rubber ring.
Using a Phillips screwdriver, unscrew the screw of the pressure plate...
...and we take it off.
Using a 24 mm wrench, loosen the nut securing the drain pipe to the pressure regulator.
Using a 5 mm Allen key, unscrew the two screws securing the fuel pressure regulator to the rail.
We separate the regulator from the ramp...
...and, having unscrewed the nut, we remove it.
The connection between the ramp and the regulator is sealed with a rubber ring.
In photos 6–10 the receiver has been removed for clarity.
The connection between the fuel pressure regulator and the tube is sealed with a rubber ring.
Install the regulator in the reverse order. If necessary, change the sealing rings and lubricate them with engine oil. The tightening torque of the regulator mounting screws is 8–11 N·m, and the drain pipe mounting nuts are 20–34 N·m.
