  Q: How to service and repair the fuel pressure regulator and reinstall the fuel pump assembly on Scion tC?

  A:

  The procedure for servicing and repairing the Fuel Pressure Regulator starts with removing the rear seat cushion assembly and rear floor service hole cover with the butyl tape removal step as the initial requirement. Discharge the fuel system pressure through engine start-up followed by switching off the ignition when the engine stops. After that, separate the fuel pump connector. Check if the engine remains off by performing a second engine crank. After ensuring engine non-start you can take off the Fuel Tank cap to clear all pressure. Remove the wire from the wire connector followed by the cable removal from the negative battery terminal. Begin removal of the fuel vacuum suction assembly and gauge tube by disconnecting the fuel tank main tube but maintain the O-ring and clean all particles from the fuel tube joint. Extract the fuel suction with pump and gauge tube from the fuel tank after removing all bolts from the fuel tank protector plate and the fuel tank vent tube set plate while preserving the fuel pump filter from damage and avoiding the fuel sender gauge arm from bending. Pull the suction tube gasket out from the fuel suction and pump assembly through its tube. To install the components start by putting on a new gasket to the fuel suction with pump and gauge tube then return it to the tank space but maintain straight positions of both the fuel pump filter and gauge arm. The installation requires full insertion of the fuel tank vent tube set plate with six bolts tightened to 6.0 N.m (60 kgf.cm, 53 in.lbf) while the fuel tank protector plate requires two bolts at the same torque for secure installation. After the connection of fuel tank main tube verify that it is free from scratches and foreign materials and that the tube joint clip remains properly secured. The rear floor service hole cover requires new butyl tape for reinstallation while the wire-to-wire connector and fuel pump connector should be connected to the floor panel convexes. The negative battery terminal gets cable connection followed by initialization steps for disconnected systems and leak detection before returning the rear seat cushion.
