• When clean fuel is visible, close the drain and switch the ignition to OFF.
• Refer to the Owner's Manual on the DVD for further details.
Fuel Filter Replacement
• With the engine off and a drain pan under the fuel filter drain hose, open the
water drain valve 1/4 turn counterclockwise and completely drain fuel and
water into the approved container.
• Close the water drain valve and remove the lid using a socket or strap wrench;
rotate counterclockwise for removal. Remove the used o-ring and discard it.
• Remove the used filter cartridge from the housing and dispose of according to
your local regulations.
• Wipe clean the sealing surfaces of the lid and housing and install the new
o-ring into ring groove on the filter housing and lubricate with clean engine oil.
• Install a new filter in the housing. Push down on the cartridge to ensure it is
properly seated. Do not pre-fill the filter housing with fuel.
• Install the lid onto the housing and tighten to 22.5 ft lbs (30.5 Nm). Do not
overtighten the lid.
• Start the engine and confirm no leaks are present.
CAUTION!
• Diesel fuel will damage blacktop paving surfaces. Drain the filter into an
appropriate container.
• Do not prefill the fuel filter when installing a new fuel filter. There is a
possibility debris could be introduced into the fuel filter during this
action. It is best to install the filter dry and allow the in-tank lift pump to
prime the fuel system.
• If the “Water In Fuel Indicator Light” remains on, DO NOT START the
engine before you drain water from the fuel filter to avoid engine damage.
EXHAUST REGENERATION
• Under certain conditions, your Cummins ® diesel engine and exhaust
after-treatment system may never reach the conditions required to remove the
trapped particulate matter. If this occurs, the “Exhaust System —
Regeneration Required Now” message will be displayed on the EVIC screen in
your cluster and you will hear one chime to alert you of this condition. Driving
your vehicle at highway speeds for as little as 45 minutes can remedy the
condition and allow the engine and exhaust after-treatment system to remove
the trapped particulate matter.
• PLEASE NOTE: Under typical operating conditions, NO indications of
regeneration state will be displayed. If you do reach 80% of filter capacity, the
following messages will assist you in inducing and understanding the
regeneration process.
