How to Remove a Fuel Injector from a Ford Diesel Engine

A fuel injector delivers fuel to engine cylinders in a specific sequence. Modern fuel injectors are typically electronically controlled, but older engines used mechanical fuel injection. For example, the large diesel engines in heavy Ford trucks made from 1987 to 1996 used mechanical injection. Removing the injectors in these vehicle also requires you clean the injection system due to the deposits left by diesel fuel.

Instructions

1

Clean the nozzle of each fuel injector and the surrounding area with clean engine oil to keep debris out of the engine when you remove the injectors. Clean the connections for the fuel lines on the injectors. Blow the injectors dry with an air compressor.

2

Release the retaining clamps for the fuel lines on the injectors. Detach the high-pressure fuel lines and the leak-off tees from the injectors. Push the fuel lines out of the way. Cover the open fuel lines with caps to keep debris out of the fuel system.

3

Turn the injectors counterclockwise with a socket wrench to loosen them from the engine. Pull the injectors from the engine with the washer still attached. Cover the injector nozzles and fuel openings with plastic caps to prevent fuel contamination.

4

Store the injectors in numbered holders as you remove them. This allows you to replace the injectors into their correct cylinder.
