2009 Toyota Yaris Parts Questions & Experts Answers

• Q: How to service and repair the fuel pressure regulator on 2009 Toyota Yaris?

  A: Service and repair operations on the fuel pressure regulator require users to begin with a Torx socket wrench E10 that allows them to take out the rear seat cushion cover pad from both hatchback and sedan models. The package tray trim panel assembly should be removed first during the installation followed by the deck board sub-assembly of the hatchback and the deck floor box and both rear seat leg covers. Detach the fuel pump connector from its location by first removing the rear floor service hole cover. To access the fuel pump connector a person must first remove the rear seat assembly. Empty the fuel system pressure while disconnecting the negative battery terminal cable. A technician can disconnect the fuel tank main tube sub-assembly by opening the tube joint clip and gently pulling it out while keeping the O-ring free from contamination through toolless and force-free procedures. Use Special Service Tools 09808-14020 and 09808-01410, 09808-01420, 09808-01430 to disconnect the fuel tank vent hose sub-assembly while removing the fuel pump gauge retainer by fitting the tool claws against the retainer tips. The technician should remove the fuel suction with pump and gauge tube assembly making sure to prevent bending the sender gauge arm while removing the fuel suction tube gasket from the fuel tank.
