Insert the injector into the delivery pipe while turning it in both directions carefully not to damage the O-ring.

Check that the injector turns smoothly. If it does not, the O-ring may be jamming, so remove the injector and check the O-ring for damage. If the O-ring is intact, insert the injector into the delivery pipe and check it for smooth rotation again.

Apply a thin coat of fresh engine oil to the O-ring. Insert the fuel pressure regulator carefully not to damage the O-ring.

Insert the fuel pressure regulator into the delivery pipe while turning it in both directions carefully not to damage the O-ring.

Check that the fuel pressure regulator turns smoothly. If it does not, the O-ring may be jamming, so remove the fuel pressure regulator and check the O-ring for damage. If the O-ring is intact, insert it into the delivery pipe and check it for smooth rotation again.

Install the throttle body gasket with its tab located as shown in the drawing.
