• Description:

  This is a genuine Ford fuel injector O-ring seal kit cataloged as O-Ring Kit for the 2020-2024 Transit van equipped with the 3.5L V6 FLEX engine. The kit supplies the injector sealing O-rings and tube seals that seal each fuel injector where it enters the cylinder head and mates to the fuel rail, containing high-pressure fuel and preventing combustion gases from escaping around the injector body. These seals ride in a hot, pressurized environment and harden, crack, or take a compression set over time, which is why Ford specifies fresh seals whenever an injector is removed. A driver needing this kit is often chasing a fuel odor, a rough idle, a hard start, a lean or rich fuel trim code, or a hissing tick that signals combustion leakage past a dried-out injector seal. Installing new O-rings restores a leak-free seal at the injector-to-rail and injector-to-head joints and prevents fuel weeping that can wash down cylinder walls or create a fire hazard. During service, lubricate the new O-rings lightly before seating the injectors, seat each injector fully and squarely to avoid pinching or rolling a seal, and inspect the injector bores for old seal debris or carbon before reassembly. These are single-use seals; the original O-rings must not be reused once disturbed, as a reused seal will not achieve the specified sealing force and can leak fuel or combustion gases. Confirm the engine application before fitting.
