SFI System: Injector: Installation

INSTALL INJECTORS AND DELIVERY PIPES
NOTE:
- Be careful not to drop the injectors when installing the delivery pipes.
- Since the O-ring may be stuck to the injector, do not put a side load on it at the removal.
1. Install a new grommet to each injector.
2. Apply a light coat of gasoline to new O-rings and install them to each injector.

7. Temporarily install the 4 nuts.
8. Install the front fuel pipe with the bolt, the 4 new gaskets and the 2 union bolts.

10. Check that the injectors rotate smoothly.
  HINT:
  
  If injectors do not rotate smoothly, the probable cause is incorrect installation of O-rings. Replace the O-rings in that case.
11. Position the injector connector outward.
12. Tighten the 4 nuts holding the delivery pipes to the lower intake manifold.
  Torque: 21 N.m (214 kgf.cm, 15 ft.lbf)
