How to Replace Injectors on a 2005 F 350

The Ford F series is a group of full-size pickups manufactured by Ford Motor Company. The model number indicates the nominal carrying capacity of the vehicle, such that an F350 is a 3/4-ton pickup truck. A 2005 F350 typically has a 6.0-liter turbo diesel engine with fuel injection. The fuel injectors deliver a precise ratio of fuel and air to the engine in a specific sequence. The replacement of the fuel injectors in an F350 will also require you to remove additional components.

Instructions

1

Remove the valve cover for the fuel injectors with a socket wrench and detach the electrical connector for the fuel injector. Disconnect the mounting bolts for the crankcase-to-head tube assembly and remove the assembly. Remove the mounting bolts for the oil rail and disconnect the oil rail.

2

Push the electrical connector for the fuel injector out of the rocker arm carrier with a small pry tool. Plug the holes for the oil drain that are next to the each glow plug with clean shop towels. Remove the mounting bolt for the fuel injector with a socket wrench and release the hold down clamp for the fuel injector. Disconnect the fuel injector and unplug the oil drain holes.

3

Install new O-rings and washers onto the new fuel injector and apply a liberal coat of clean engine oil to the fuel injector. Install the fuel injector and attach the hold-down clamp for the fuel injector. Torque the mounting bolt for the fuel injector to 24 foot-pounds with a torque wrench.

4

Place the electrical connector for the fuel injector into the rocker arm carrier with the pry tool. Lubricate the O-rings on the top of the fuel injector with clean engine oil.

5

Place the oil rail into position onto the fuel injectors and press down on the oil rail to secure it in place. Torque the mounting bolts for the oil rail to 10 foot-pounds with a torque wrench.

6

Attach the crankcase-to-head tube assembly to the engine and torque the mounting bolts to 60 foot-pounds with a torque wrench. Connect the electrical connector for the fuel injector and install the valve covers with a socket wrench.
