How to install the fuel injector assembly and related components on Toyota Prius?

Install each of the fuel injectors by using spindle oil or gasoline to lubricate a fresh O-ring before placing it on the assembly. Before mounting the fuel injector on the delivery pipe apply a thin layer of spindle oil or gasoline to guide its O-ring contact area then coat the O-ring again before rotating it right and left toward the delivery pipe while ensuring the O-ring stays undamaged and snug against the fitment. Smooth rotation of the fuel injector serves as a indicator for proper O-ring condition; swap out the O-ring if the fuel injector shows any resistance. Install new insulators to both the cylinder head and the two No. 1 delivery pipe spacers by maintaining correct installation direction. Screw the 4 fuel injectors into the fuel delivery pipe after temporarily tightening its 3 bolts but avoid allowing the injectors to drop. First verify that fuel injection components turn without resistance before replacing the O-ring. Use the following torques for final bolt tightening: 19 Nm (194 kgf-cm) for bolt A while bolt B requires 9.0 Nm (92 kgf-cm). Educate the technician to connect the fuel tube to the fuel delivery pipe by inserting the joint until a "click" sound is produced and inspect both ends of the connection. Fasten the fuel pipe clamp known as No. 1. Follow by inserting the cylinder head cover sub-assembly before you put the reservoir bracket into place with bolt number 1 and secure all 3 bolts to 8.5 Nm (87 kgf-cm, 75 in-lbf) using the correct sequence. The hose clamp should receive the connector clamp together with the wire harness clamp and No. 2 fuel vapor feed hose. The installation of the brake master cylinder reservoir sub-assembly requires installation of the reservoir followed by tightening its two bolts to 8.5 Nm (87 kgf-cm, 75 in-lbf) then completion of switch connector connection. The correct procedure for installation includes securing the air cleaner assembly followed by attaching the front outer cowl top panel sub-assembly using 7 bolts tightened to 6.4 Nm (65 kgf-cm, 57 in-lbf). Additionally, the process involves connecting the 4 wire harness clamps and installing the No. 2 engine room relay block with 2 bolts tightened to 8.4 Nm (86 kgf-cm, 74 in-lbf). The mechanic must attach the windshield wiper motor and link before connecting the cable to the negative battery terminal while inspecting for fuel leaks while performing initialization because some systems require post-cable disconnect initialization.
