COMPONENTS





INSTALLATION

1. INSTALL FUEL INJECTOR ASSEMBLY





(a) Apply a light coat of gasoline or spindle oil to a new O-ring, then install it onto each fuel injector.





(b) Apply a light coat of gasoline or spindle oil to the fuel delivery pipe which comes into contact with the O-ring of the fuel injector.
(c) Apply a light coat of gasoline or spindle oil to the O-ring again, then install the fuel injector right and left onto the fuel delivery pipe.

NOTE: Make sure that the O-ring is not cracked or jammed when installing.

(d) Check that the fuel injector rotates smoothly.
If the fuel injector does not rotate, replace the O-ring.
2. INSTALL FUEL DELIVERY PIPE SUB-ASSEMBLY





(a) Install 4 new insulators into the cylinder head (A).
(b) Install the 2 delivery pipe No. 1 spacers onto the cylinder head (B).

NOTE: Make sure that the delivery pipe No. 1 spacers are installed in the correct direction.





(c) Install the fuel delivery pipe together with the 4 fuel injectors, then temporarily tighten the 3 bolts (C).

NOTE: Do not drop the fuel injectors when installing the fuel delivery pipe.

(d) Check that the fuel injector rotates smoothly (D).
If the fuel injector does not rotate, replace the O-ring.
(e) Tighten the 3 bolts to the specified torque (E).
Bolt A - Torque: 19 Nm (194 kgf-cm, 14 ft-lbf)
Bolt B - Torque: 9.0 Nm (92 kgf-cm, 80 in-lbf)





(f) Connect the fuel tube (F).
(1) Align the fuel tube connector with the pipe, then push the fuel tube connector in until the retainer makes a "click" sound to connect the fuel tube to the pipe.

NOTICE:
- Check that there are no scratches or foreign objects around the connected part of the fuel tube connector and pipe before performing this work.
- After connecting the fuel tube, check that the fuel tube is securely connected by pulling the fuel tube connector.

(h) Install the 3 wire harness clamps (H).
(i) Connect the 4 fuel injector connectors (I).
3. CONNECT VENTILATION HOSE





(a) Connect the ventilation hose to the cylinder head cover.

NOTE: Make sure that the hose clamp is at the correct angle when installing.

4. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Torque: 5.4 Nm (55 kgf-cm, 48 in-lbf)
5. INSPECT FOR FUEL LEAK (Testing and Inspection)

6. INSTALL NO. 2 CYLINDER HEAD COVER
