Installation - Engine-mounted fuel filter 1. Install the new filter into the filter bracket. Turn the filter clockwise to lock it in place. 2. Reconnect both fuel lines. Using a fuel which has more than average impurities may require the fuel filter to be replaced more frequently than the service interval specifies. The system will need to be purged of air after removal/changing of the filter. See Purging air from the fuel system after DFCM and engine-mounted fuel filter replacement following. Purging air from the fuel system after DFCM and engine mounted fuel filter replacement Turn the ignition key to on for 30 seconds, then turn it to off. Do this a total of six times in a row to purge any trapped air from the fuel system. After filter service, a no start or rough running engine may indicate that air is entering the system through the filter bowl seal or drain. Make sure the drain is tight and the filter bowl has been tightened to the mechanical stop. DIESEL EXHAUST SYSTEM: OXIDATION CATALYST/DIESEL PARTICULATE FILTER SYSTEM Your vehicle is equipped with a diesel particulate filter (DPF). The DPF is an inline filter in the exhaust system which reduces carbon emissions by trapping exhaust particles before they reach the tailpipe. The DPF looks similar to a traditional exhaust catalyst, except larger, and is part of the exhaust system under the vehicle. The DPF is coupled to a diesel oxidation catalyst, that reduces the amount of harmful exhaust emitted 34 2013 Diesel (67l) Supplement, 1st Printing USA (fus)
