2014 Ram 2500 fuel pump

*No. 1 Ultra Low Sulfur Diesel Fuel should only be used
where extended arctic conditions (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Ultra Low Sulfur Diesel Fuel or
Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.•Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low
Sulfur Diesel Fuels which reduces the temperature at
which wax crystals form in fuel.
•The fuel grade should be clearly marked on the pump
at the fuel station.
•The engine requires the use of“Ultra Low Sulfur
Diesel Fuel”. Use of incorrect fuel could result in
engine and exhaust system damage. Refer to “Fuel
Requirements” in “Starting And Operating” for fur-
ther information.
•Commercially available fuel additives are not neces-
sary for the proper operation of your Cummins®
diesel engine. However, if seasonably adjusted fuel is
not available and you are operating below 20°F (-6°C),
Mopar® Premium Diesel Fuel Treatment (or equiva-
lent) may be beneficial to avoid fuel gelling.

ENGINE RUNAWAY
Diesel engine runaway is a rare condition affecting diesel
engines, where the engine consumes its own lubrication
oil and runs at higher and higher RPM until it overspeedsto a point where it destroys itself due to either mechani-
cal failure or engine seizure through lack of lubrication.
WARNING!
In case of engine runaway due to flammable fumes
from fuel spills or turbocharger oil leaks being
sucked into the engine, do the following to help
avoid personal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire extinguisher,
direct the spray from the fire extinguisher into the
grille on the passenger side so that the spray enters
the engine air intake.
The inlet for the engine air intake is located behind
the passenger side headlamp and receives air
through the grille.

STARTING AND OPERATING 247

NOTE:Ensure funnel is inserted fully to hold flapper
door open.
3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior to
putting back in the jack kit.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
•A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.

ADDING FUEL — CHASSIS CAB MODELS
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
•Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be burned.
Always place fuel containers on the ground while
filling.
Fuel Filler Cap
If the fuel filler cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap. A poorly fitting cap could let impuri-
ties into the fuel system.
256 STARTING AND OPERATING

CAUTION!
•To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
(Continued)
CAUTION!(Continued)
•DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
•When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.
•Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
Filling The DEF Tank
260 STARTING AND OPERATING

•Electronically-heated DEF lines
•DEF control module
•NOx sensors
•NH3 sensor
•Temperature sensors
•SCR catalyst
The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center (EVIC)”
in “Understanding Your Instrument Panel” for system
messages and warnings.NOTE:
•Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise.
This is normal operation.
•The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation.
280 STARTING AND OPERATING

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.
1. Ensure engine is turned off.
2. Place drain pan under the fuel filter drain hose.
3. Open the water drain valve 1/4 turn counterclockwise
and completely drain fuel and water into the ap-
proved container.
4. Close the water drain valve.5. Remove lid using a socket or strap wrench. Rotate
counterclockwise for removal. Remove used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and
dispose of according to your local regulations.
7. Wipe clean the sealing surfaces of the lid and housing.
8. Install new o-ring back into ring groove on the filter
housing and lubricate with clean engine oil.
9. Remove new filter cartridge from plastic bag and
install into housing.
NOTE:Do not remove cartridge from bag until you reach
this step in order to keep cartridge clean.
10. Push down on the cartridge to ensure it is properly
seated.Do not pre-fill the filter housing with fuel.
11. Install lid onto housing and tighten to 22.5 ft lbs (30.5
N.m). Do not overtighten the lid.
