How to Replace Injectors on a 6 0 Diesel Engine
The Ford 6.0 Power Stroke is an eight-cylinder 6.0-liter engine that Ford has manufactured since 2003. It is a diesel engine that Ford most often uses in large vehicles such as 3/4-ton and 1-ton pickups. The function of the fuel injectors is to deliver fuel in a precise timing and quantity. You can replace the fuel injectors on the Ford 6.0 diesel engine without removing the fuel rail, unlike most gasoline engines.

Remove the valve covers with a socket wrench and detach the electrical connectors from the fuel injectors. Disconnect the mounting bolts for the crankcase-to-head tube assembly and remove the assembly from the crankcase.
2Disconnect the oil rail from the engine. Push the electrical connector for the fuel injector out of the rocker arm carrier with a small pry tool.
3Plug the oil drain holes next to the glow plugs with clean cloth. Disconnect the retaining bolt for the fuel injectors with a socket wrench and release the hold-down clamp.
4Pry the fuel injectors from the engine with a Snap-On SDMT440 Torx tool so that you dont damage the fuel injectors. Discard the O-rings and copper washer on the fuel injector. Pull the cloth from the oil drain holes.
5Mount new O-rings and copper washers to the fuel injectors. Coat the fuel injector assembly with clean engine oil and install the fuel injector. Attach the hold-down clamp for to the fuel injector and torque the mounting bolts to 24 ft. lbs. with a torque wrench.
6Place the electrical connector for the fuel injector electrical into the rocker carrier. Lubricate the top O-rings on the fuel injector with engine oil.
7Install the oil rail into the fuel injectors so that the mounting feet of the oil rail are flush with their mounting surface on the engine. Install three guide bolts to hold the oil rail in place.
8Install six of the nine mounting bolts for the oil rail. Replace the three guide bolts with the three remaining mounting bolts. Tighten all nine mounting bolts to 10 ft. lbs. with a torque wrench.
9Connect the crankcase-to-head tube assembly and tighten the mounting bolts to 60 ft. lbs. with a torque wrench. Attach the electrical connector to the fuel injector and install the valve covers.
