• Q: How to install the fuel injector assembly on 2009 Scion tC?

  A: The first step of fuel injector assembly installation requires applying gasoline or spindle oil to new O-rings before installing one onto each fuel injector. First put a small amount of gasoline or spindle oil on the fuel delivery pipe section touching each fuel injector O-ring before putting another light coating of oil on the O-ring before mounting the fuel injector to the pipe while checking for proper O-ring fitment and damage. The fuel injectors need to rotate without issues; if they do not one should replace the O-ring. The fuel delivery pipe sub-assembly requires new insulators to be placed into the cylinder head before adding the two delivery pipe spacers. Secure the delivery pipe with its attached four injectors while taking care to prevent injector loss but avoid overtightening the bolts. Carefully confirm that every fuel injector rotates without Resistance before re-tightening the bolts to 20 Nm (205 kgf-cm, 15 ft-lbf). The system requires connection of 4 fuel injector connectors as well as wire harness clamp installation. The ventilation hose No. 2 requires connection to the ventilation valve while maintaining a proper position between the hose clamp and paint mark. The procedure includes connecting the fuel main tube by pushing the fuel tube connector until it clicks before installing the fuel pipe clamp to seal the fuel tube within the fuel hose clamp. To complete the installation finish by putting on the air cleaner cap sub-assembly alongside the engine cover sub-assembly and attach the cable to the negative battery terminal while also checking for fuel leaks and executing initialization with the understanding that selective systems need initialization upon reconnecting the negative (-) battery cable.
