• Q: How to install the fuel injector assembly on 2010 Scion xB?

  A: Before installing the 2AZ-FE engine fuel injector assembly you should apply gasoline or spindle oil to new O-rings and place them on each fuel injector. Before installing the right and left fuel injectors into the fuel delivery pipe, apply a layer of gasoline or spindle oil onto both the O-ring then the contacting portion of the pipe. Ensure the O-ring remains intact without damage or jamming. Run a smoothness test of the fuel injector because a malfunctioning unit requires an O-ring swap. Install four insulators onto the cylinder head before setting the two delivery pipe spacers. Attach the fuel delivery pipe that contains the 4 fuel injectors but only tighten the 2 bolts carefully without allowing the injectors to fall. For fuel injector inspection check for easy rotation and replace the O-ring when required before applying a torque of 20 Nm (204 kgf-cm, 15 ft-lbf) to the 2 bolts. After fuel injector connector attachment together with wire harness clamp installation complete the procedure by connecting the No. 2 ventilation hose to the ventilation valve. Safely position the paint mark and hose clamp angle of the No. 2 ventilation hose in correct alignment with the ventilation valve before attachment. To complete the connection of the fuel main tube push the fuel tube connector until it clicks and finish by installing and securing the No. 2 fuel pipe clamp. The final step includes fixing the air cleaner cap sub-assembly with hose followed by fuel leak inspection before securing the No. 1 engine cover sub-assembly.
