How to Replace Injectors in a 1988 Ford Diesel
- 1). Release the clamps on the fuel lines to the fuel injectors and disconnect the fuel lines with a flare nut wrench. Discard the gaskets for the fuel lines and push the fuel lines to the side so you can access the fuel injectors.
- 2). Cover the top end of the fuel injectors with plastic caps to keep them clean. Turn the fuel injectors counterclockwise and pull them from the engine. Record the cylinder of each fuel injector as you remove it. Cover the nozzle end of the fuel injectors with plastic caps.
- 3). Remove the copper gasket from the nozzle of each fuel injector with tool T71P-19703-C and discard the gasket. Clean the bore of the fuel injectors with tool T83T-9527-A and blow compressed air into the bore to remove any carbon or metal particles.
- 4). Remove the cap from the nozzle of each fuel injector. Apply a small amount of grease to the nozzle and install a new copper gasket to the fuel injector.
- 5). Apply an anti-seize compound to the fuel injector threads to prevent the injectors from sticking. Install the fuel injector to its correct cylinder head and tighten it to 33 ft. lbs. with a torque wrench. Remove the protective caps from the open end of the fuel injectors.
- 6). Install new O-rings on the fuel return line and connect the fuel lines to the fuel injectors with a flare nut wrench. Attach the clamps for the fuel lines. Start the engine and check for fuel leaks.
