So Fix it

How do I Replace 7 3L Diesel Injectors

Ford manufactured its eight-cylinder, 7.3-liter Power Stroke diesel engine from 1994 to 2002. This engine was a complete redesign from Fords previous 7.3-liter engine and featured electronic control with direct fuel injection. This engine is common in heavy Ford trucks, and is the standard engine for the 2002 Ford F350 Super Duty truck with four-wheel drive. The replacement of the fuel injector in this vehicle requires special tools and the removal of additional components to access the injectors.

Instructions

1

Disconnect the valve cover with a socket wrench, and unplug the electrical connectors from the fuel injectors. Remove the drain plugs from the oil rail to keep oil out of the combustion chamber while you replace the fuel injectors.

2

Remove the retaining screw for the oil deflector with a socket wrench and disconnect the oil deflector. Disconnect the retaining bolt for the fuel injector.

3

Remove the fuel injector from the injector bore with Injector Remover No. T94T-9000-AH1 and discard the copper washers. Loosen any debris in the injector bore with Rotunda Injector Sleeve Brush 104-00934-A and clean the injector bore with a shop towel.

4

Install new copper washers on the new fuel injectors and lubricate the injectors with engine oil. Push the fuel injectors into the injectors bore to seat the O-rings. Seat the fuel injectors into the injector bores with Injector Replacer No. T94T-9000-AH2.

5

Install the oil deflector and tighten its retaining bolt to 108 inch-pounds with a torque wrench. Replace the drain plug on the fuel rail and tighten it to 96 inch-pounds. Install the drain plug on the oil rail and tighten it to 53 inch-pounds. Connect the wiring harness for the fuel injector and install the valve cover with a socket wrench.
