FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel (15
ppm Sulfur maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting
ASTM (formerly known as the American Society for
Testing and Materials) specification D-975 Grade S15 will
provide good performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is required to
operate at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or dilute the No.
2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the
fuel filters.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided on both fuel filters. If you buy good
quality fuel and follow the cold weather advice above,
fuel conditioners should not be required in your vehicle.
If available in your area, a high cetane “premium” diesel
fuel may offer improved cold-starting and warm-up
performance.

CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
Fuel Specifications
The Cummins® diesel engine has been developed to take
advantage of the high energy content and generally
lower cost No. 2 Ultra Low Sulfur diesel fuel or No. 2
Ultra Low Sulfur climatized diesel fuels. Experience has
shown that it also operates on No. 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.NOTE:
•If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, Do not start the vehicle. If you
restart your vehicle you risk damage the engine and
fuel system. Please call your local dealer for service.
•A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your Cummins®
diesel engine. (Chassis Cab models not configured
with B20 capability.)
•A maximum blend of 20% biodiesel meeting ASTM
specification D-7467 may be used with your Cum-
mins® diesel engine. (Pickup models and Chassis Cab
models configured with B20 Capability.)
•In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
mins® diesel engine.

Fuel Quality — Must Comply With ASTM
Standards
The quality of Biodiesel fuel may vary widely. Only fuel
produced by a BQ9000 supplier to the following specifi-
cations may be blended to meet Biodiesel blend (B6–B20)
fuel meeting ASTM specification D-7467:
•Pretrodiesel fuel meeting ASTM specification D-975
and Biodiesel fuel (B100) meeting ASTM specification
D-6751.
Fuel Oxidation Stability — Must Use Fuel Within
Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which can
result in long term storage problems. Fuel produced to
approved ASTM standards, if stored properly, provides
for protection against fuel oxidation for up to six months.
Fuel Water Separation — Must Use MOPAR®/
Cummins® Approved Fuel Filter Elements
You must use MOPAR®/Cummins® approved fuel filter
elements in both your engine mounted filter and frame
mounted filter.
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your MOPAR®/
Cummins® filtration system is designed to provide ad-
equate fuel water separation capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tem-
peratures, which may pose problems for both storage and
operation. Precautions can be necessary at low ambient
temperatures, such as storing the fuel in a heated build-
ing or a heated storage tank, or using cold temperature
additives.

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel filler cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” Thesemicrobes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.

Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.
1. Install the air cleaner filter element into the housing
assembly with the air cleaner filter inspection surface
facing downward.
2. Install the air cleaner cover onto the housing assembly
locating tabs.
3. Install screws to secure the air cleaner cover to the
housing assembly.
Draining Fuel/Water Separator Filter
There are two fuel filter assemblies. One is located on the
driver’s side of the engine. The best access to this water
drain valve is from under the hood. The second one is on
the under body, located in front of the rear axle above the
drive shaft on pick-up models. The Chassis Cab modelssecond filter location is on the frame behind the front
axle. The best access to this water drain valve is from
under the vehicle.
CAUTION!
•Do not drain the fuel/water separator filters when
the engine is running.
•Diesel fuel will damage blacktop paving surfaces.
Drain the filters into an appropriate container.
If water is detected in the water separator while the
engine is running, or while the ignition switch is in the
ON position, the “Water In Fuel Indicator Light” will
illuminate and an audible chime will be heard five times.
At this point you should stop the engine and drain the
water from both of the filters.
300 MAINTAINING YOUR VEHICLE
Page 303 of 360

CAUTION!
If the “Water In Fuel Indicator Light” remains on, DO
NOT START the engine before you drain water from
the fuel filters to avoid engine damage.
If the “Water In Fuel Indicator Light” comes on and a
single chime is heard while you are driving, or with the
ignition switch in the ON position, there may be a
problem with your water separator wiring or sensor. See
your authorized dealer for service.
Upon proper draining of the water from both fuel filters,
the “Water In Fuel Indicator Light” will remain illumi-
nated for approximately 10 seconds. If the water was
drained while the engine was running, the “Water In Fuel
Indicator Light” may remain on for approximately three
minutes.NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately dis-
carded, can present a problem to the environment. Con-
tact an authorized dealer, service station, or government
agency for advice on recycling programs and for where
used fluids and filters can be properly disposed of in
your area.
Drain the fuel/water separator filters when the “Water In
Fuel Indicator Light” is ON. Within 10 minutes of vehicle
shutdown, turn the engine mounted filter drain valve
(located on the side of the filter assembly) counterclock-
wise 1/4 turn, and turn the under body mounted filter
drain valve (located on the bottom of the filter assembly)
counterclock wise 1 full turn. Then turn the ignition
switch to the ON position, and allow any accumulated
water to drain. Leave the drain valve open until all water
and contaminants have been removed. When clean fuel is
visible, close the drain valves by turning them fully
clockwise, and turn the ignition switch to OFF.
