7.3L Fuel Injector (2004-99)


Test fuel for contamination. If any is found, clean the entire fuel system prior to installing any new components

Tighten the fuel injector outboard retaining bolts and oil deflector to 12n.m (9 ft.lb torque)

Drain oil and coolant prior to injector removal just in case injector cup comes out with injector

Verify copper washer from old injector was not left in the injector cup

Oil and fuel must be removed from the cylinders prior to instillation of the injector

Verify electrical connections (valve cover, pigtail, etc.) are in good condition
