Fuel injection nozzle (1) Connection for the union nut of the fuel supply line (2) Threaded hole for the banjo bolt of the leak off line (3) Union nut on the fuel injection nozzle (4) Wire clip (5) Seat washer (1) Tighten the union nut of the high pressure fuel line (not shown) to the following torque: ... 22 N m (16 lb ft) (2) Tighten the banjo bolts for the leak off tubing (not shown) to the following torque: ... 9.0 N m (80 lb in) (3) Tighten the union nut on the fuel injection nozzle to the following torque: ... 30 N m (22 lb ft)Note: When the fuel injection nozzle is installed, put a 2.0 mm (0.08 inch) bead of 4C-5591 Anti-Seize Compound on the first two threads of the union nut. (4) Wire clip (5) Seat washerNote: Remove the original seat washer from the threaded hole for the fuel injection nozzle which is located in the cylinder head. If the original seat washer is not removed, the projection of the nozzle will be incorrect when a new seat washer is installed. Do not reuse seat washer (5) .Bench test the fuel injection nozzles at a temperature of 18 to 20 °C (64 to 70 °F).Note: Use clean SAE J-967 oil (ISO 4113) when you are conducting the test. The oil is available in 5 gallon containers ( 6V-6068 Calibration Fluid ) and 55 gallon containers ( 6V-6067 Calibration Fluid ). If dirty oil is used for the test, the components of the fuel injection nozzle will be damaged.Refer to the Systems Operations, Testing and Adjusting Module, "Fuel Injection Nozzle - Test" topic for additional information on testing the fuel injection nozzles.

( 1 ) The code letters are stamped on the side of the fuel injector body. The code letters are located below the connection for the nut of the high pressure fuel line.Note: Ensure that the new fuel injection nozzles have the same identification code as the nozzles which were originally installed in the cylinder head.Leakage in 10 seconds ... 0 drops
