Installation Notes and Tips

Confirm injector and seal dimensions before installation, and replace only with the correct application-specific seal kit. Clean the injector and mating surfaces thoroughly before fitting the new O-rings, and lubricate seals with clean engine oil or approved assembly lubricant to reduce damage during installation. Verify proper seating after assembly and inspect for leaks once the fuel system is pressurized.
