Remove the protection covers from the fuel line connections.  Put the injection fuel lines in position, and install the nuts until they are finger tight. 2. Install the spacers and bolts (2) that hold the fuel injection lines to the cylinder head. 3. Use tool (A) and tighten nuts (1) to a torque of 40 + 7 N•m (30 + 5 Ib. ft.). NOTICE Do not let the tops of the fuel nozzles turn when the fuel lines are tightened.  If the tops of the nozzles turn, the nozzles will be damaged. 4. Use tool (A), a wrench, and a torque wrench to tighten nuts (3).  Tighten nuts (3) to a torque of 40 + 7 N•m (30 + 5 Ib.ft.). 5. Remove (bleed) the air from the fuel lines.  See Priming The Fuel System in the Maintenance Guide.

START BY: a. remove fuel injection lines NOTE: The illustrations which follow are of a 3306 Engine. 1. Remove bolt (1) and clamp (2) from the fuel injection nozzles to be removed. 2. Install tool (A) with the inside lip of the puller on the lower stepped diameter of the nozzle and the tip of the button in the threaded hole for bolt (1). NOTICE Do not exceed a torque of 17 N•m (150 Ib. in.) on the screw in tooling (A) during removal of the nozzle. Added force can cause the stem of the nozzle to bend or break off. 3. Tighten the screw in tooling (A) to a maximum torque of 17 N•m (150 Ib. in.) to remove fuel injection nozzle (3). 10
