Turn the engine on and look for weeping or dripping where fuel rail, fuel line and fuel pressure regulator are located. Make sure that the fuel pressure is correct, and that the pressure regulator is working its magic. However, if the pressure regulator is bad or leaking the unit should be replaced. 1, reduce the fuel pressure from the fuel pump of the car and pull the cable from the negative terminal of the battery. Wipe the vicinity of the fuel pressure regulator on the fuel rail. Remove the vacuum line from the regulator and for a 2.2L engine, unscrew the banjo bolt and discard the sealing washers and the fuel return line, unscrew the clamp screw and take out the regulator. On 2.6L four-cylinder and 3.2L V6 engines: loosen the hose clamp and disconnect the fuel return line from the bottom of the regulator, next, remove the retaining bolts and remove the regulator from the fuel rail. Remove the old O-ring and replace it with a new one; it is advisable to grease the O-ring with a bit of oil. The pressure regulator should then be positioned back on the fuel rail, and either bolted in place or clipped in place by a clamp as the fuel return has to be connected back to the fuel rail and all connections need to be very tight. Connect back the vacuum hose to the regulator then make sure that it fits perfectly in its place. Last but not least, crank the engine and observe for fuel leaks around the fuel pressure regulator, will take some time to start the engine since the fuel line has trapped air inside.
