Q: How to service and repaire the fuel pressure regulator and reassembling the fuel pump components on Scion tC?
A: Start fuel pressure regulator service by removing the fuel sender gauge assembly through the removal of its two claw fittings followed by sliding it out from the fuel filter. background chaos The fuel suction plate sub-assembly requires extraction through disconnection of connectors while utilizing a taped screwdriver to separate four claw fittings from all components yet keep the fuel suction plate protected. Start by moring away the fuel pump harness by unplugging the 2 terminals of the pump and removing the connector. Separating the 5 claws fittings with a taped-wrapped screwdriver will allow removal of the No. 2 fuel suction support but the technician must take care to protect the fuel suction support and fuel tank fuel filter from damage. Extract first the fuel pump cushion rubber from the fuel pump and then use fingertips to remove the entire fuel pump from the fuel filter. Usage of a small screwdriver enables users to detach the fuel pump filter from its clip before the pump filter reaches removal. The removal process for the fuel pressure regulator assembly requires pulling it out from the fuel tank fuel filter after extracting the O-ring. Staff should lubricate a new O-ring with spindle oil or gasoline before installing it into the fuel pressure regulator then pressing the regulator into position within the fuel tank fuel filter while checking for O-ring damage. After installing the fuel pump filter onto the pump, users should place a new clip on it to secure it. A thin layer of gasoline or spindle oil should be applied to the O-ring before inserting the fuel pump into the fuel tank fuel filter while checking that the O-ring is not broken or stuck. During installation position the claw points correctly on the cushion rubber before fixing the rubber onto the fuel pump and adding the No. 2 fuel suction support to the fuel filter. The installation of 2 pump harness terminals should be followed by connecting the pump harness connector. Apply gasoline or spindle oil with a thin layer to the O-ring in the fuel suction plate before placing it onto the fuel filter while checking that the O-ring remains undamaged inside its claws then attach the fuel test harness. The last step involves fitting the fuel sender gauge into its claw positions.
