INSTALLATION

1. Apply gasoline to the new O-ring.

CAUTION

Do not allow gasoline to enter the fuel rail.
2. Insert the fuel pressure regulator into the fuel rail while

rotating the injector from side to side, taking care not to
damage the O-ring.

3. Check that the fuel pressure regulator rotates smoothly. If it

does not rotate smoothly, the O-ring may be caught.
Remove the fuel pressure regulator and check the O-ring for
damage. Then, insert it again into the fuel rail and check.
