Service of the fuel pressure regulator starts by draining fuel system pressure and taking off the negative battery cable. The intake air connector requires removal alongside the No. 2 fuel hose disconnection. The procedure for removing the fuel pressure regulator begins by disconnecting three components including throttle with motor body connectors, VSV connector, and engine wire harness clamp. Begin by removing the bolt to detach the harness clamp bracket before proceeding to remove the three securing bolts connected to the fuel pressure regulator. The installer must apply a thin layer of gasoline or spindle oil to the O-ring then use the three bolts to mount the fuel pressure regulator with 8.5 N.m torque speed (87 kgf.cm, 75 in.lbf). Install the harness clamp bracket by bolting it in place with a torque of 8.2 N.m (84 kgf.cm, 73 in.lbf). Reestablish the attachment of the engine wire harness clamp together with the VSV connector and throttle with motor body connectors. Connect the No. 2 fuel hose while reinstalling the intake air connector and reestablish the cable connection to the negative battery terminal where torque should be 3.9 N.m (40 kgf.cm, 35 in.lbf). Finally, check for fuel leakage.
