• Description:

  This is a genuine Ford Motorcraft fuel injector O-ring kit for the 7.3L Power Stroke turbo diesel used in Super Duty and E-Series applications. The kit supplies the sealing O-rings that seat the fuel injectors in the cylinder head and seal the fuel and oil passages around each injector body. On the 7.3L HEUI system the injectors are actuated by high-pressure oil and supplied by the fuel rail, so intact O-rings are essential to keep fuel and oil contained at each injector and to maintain proper injection pressure. Owners install this kit when servicing or replacing injectors, and when chasing symptoms such as fuel or oil leaks around the injectors, rough running, hard starting, loss of power, or oil and fuel cross-contamination caused by hardened, cracked, or swollen O-rings. Worn injector O-rings are a common source of weeping and pressure loss on high-mileage 7.3L engines. Built to Ford Motorcraft specifications, the kit provides the correct O-ring sizes and material to reseal the injectors to factory standards without modification. It replaces earlier service numbers for the same application. Confirm the engine is the 7.3L diesel before ordering, lubricate the new O-rings during assembly, and reseal every injector that is disturbed so each one seats and seals correctly after the work is complete.
