Installation Procedure

1. Install the fuel pressure regulator to the fuel rail.
2. Secure the fuel pressure regulator with two bolts.
TIGHTEN
^ Fuel pressure regulator bolts to 9.3 Nm (82 lb. in.).





3. Install the new O-rings and grommets to each of the injectors.





4. Install the four injectors to the fuel rail, positioning injector connectors upward.
5. Install the four new insulators and two spacers in position on the intake manifold.
6. Place the fuel injectors with the fuel rail to the intake manifold.
7. Secure fuel injector and fuel rail with two bolts. Do not tighten fully.

NOTE: Check that the fuel injectors rotate smoothly. If the injectors do not rotate smoothly, the probable cause is incorrect installation of the O-rings. Replace the O-rings if necessary and position the injector connector upward.
