SUBJECT:
Fuel And Fuel Filtering Requirements For Cummins 5.9L And 6.7L Engines
OVERVIEW:
This bulletin involves a discussion regarding fuel system requirements.
MODELS:
2006 - 2007 (DH/D1/DC) Ram Truck (Heavy Duty)
NOTE: This bulletin applies to vehicles equipped with a 5.9L High Output or a 6.7L
Cummins Turbo-Diesel Engine (sales codes ETH or ETJ respectively) that
were built on or after March 07, 2006 (MDH 0307XX).
DISCUSSION:
Current Fuel Systems:
- For the diesel engine system to operate at its peak performance a high level of fuel
quality must be maintained. Emission control and fuel delivery systems have advanced
significantly. Care must be taken to insure that the fuel that is delivered to the engine fuel
injection system is of the highest quality possible and free of contaminants.
- Significant components to fuel quality are: the initial quality of the fuel (as dispensed from
the service station fuel pump or bulk storage), on-vehicle fuel storage, and the on-vehicle
fuel filtering of the diesel fuel prior to the fuel injection process.
- Refer to the Owners Manual for fuel and fuel system information.
Proper Fuel And Fuel Quality:
- Use good quality diesel fuel from a reputable supplier. It is recommended that purchase
of diesel fuel should be made from a service station that is known to dispense a high
volume of highway diesel fuel.
- Ultra Low Sulfur Highway Diesel Fuel (15 ppm of sulfur or less and meeting ASTM D975
- grade S-15) is required for use in Dodge Ram Trucks equipped with a 6.7L diesel engine
and a NOx absorber
- Ultra Low Sulfur Highway Diesel Fuel (preferred) or Low Sulfur Highway Diesel Fuel (500
ppm of sulfur or less) are required for use in Dodge Ram Trucks equipped with a 5.9L
diesel engine. If the 2007 Ram Truck (DC) Cab and Chassis is equipped with a 6.7L diesel
engine and no NOx absorber, then this vehicle engine may use either Ultra Low Sulfur
Highway Diesel Fuel (preferred) or Low Sulfur Highway Diesel Fuel (500 ppm of sulfur or

less).
- A maximum blend of 5% biodiesel (B5) is acceptable as long as the biodiesel mixture
meets ASTM specification D-975, D-975 - grade S-15, and ASTM D6751. A biodiesel fuel
blend that is higher than 5% is not acceptable without additional fuel processing because
these higher percentage biodiesel blends contain excess amounts of moisture which
exceed the water stripping capability of the on-engine final fuel filter. Should a higher
percentage biodiesel fuels be used an auxiliary water stripping filter will be required.
- A maximum blend of 20% biodiesel (B20) can be used by government, military, and
commercial fleets who equip their vehicle(s) with an optional water separator, and adhere
to the guidelines in the Department of Defense specification A-A-59693 (in addition to:
ASTM specification D-975, D-975 - grade S-15 and ASTM D6751)
- Off-highway diesel fuel (i.e. farm or marine use diesel fuel) that does not meet Ultra Low
Sulfur Highway or Low Sulfur Highway fuel specifications (as listed above) is NOT
acceptable. Unknown sulfur and water content and unknown cetane number may
adversely affect the performance of the engine and fuel injection system.
- Fuel conditioners (additives) are not recommended and should not be required if you buy
good quality fuel and follow cold weather advice supplied in the Owners Manual.
Proper Bulk (Off-Vehicle) Fuel Storage:
- Proper maintenance of stored fuel is essential. Diesel fuel is seldom entirely free of
moisture. Fuel contaminated with moisture may develop a bacteria or “slime” that may
restrict or block fuel filters and lines.
- As diesel fuel is lighter than water, drain condensation no less than monthly from the
diesel fuel supply/storage tanks.
- Change the storage tank in-line filter regularly. This filter acts as the last filter prior to the
diesel fuel entering the vehicle diesel fuel tank. Good quality diesel fuel is mandatory. If the
storage tank does not have an in-line filter, then a in-line filter should be added. Refer to
the table on the following page for recommended in-line filter specifications.
Proper On-vehicle Fuel Storage And Filtering:
- Proper on-vehicle fuel storage that prevents fuel contamination is important.
- The original (OEM) vehicle fuel tank module (fuel pickup) filter performs a primary filtering
of the on-vehicle diesel fuel as the fuel leaves the fuel tank and enters the fuel lines.
- On-vehicle auxiliary diesel fuel tanks are often added by the vehicle owner to extend
vehicle driving range. Auxiliary fuel tank systems must protect the quality of the diesel fuel
just as well as the originally equipped (OEM) fuel tank that came with the vehicle when it
was new.
- On-vehicle auxiliary diesel fuel storage tanks must have a primary fuel filter to prevent
contamination and moisture accumulation. Refer to the table on the following page for
recommended filter specifications.
- The prevention of moisture in the fuel system, the prevention of fuel stagnation, and the
use of a primary fuel filter should all be considered in the purchase, installation, and
maintenance of any auxiliary on-vehicle diesel fuel tank.

Proper On-vehicle Final Fuel Filtering:
- The large fuel filter mounted at the engine is the final fuel filter, water separator, fuel
heater, and water drain. This filter is the final “line of defense” when maintaining a high
level of fuel quality. If the diesel fuel is contaminated or contains moisture, the engine
mounted fuel filter system is the last chance to affect possible correction.
- The quality of the fuel, its prior storage, and fuel handling prior to the final filter all have a
significant impact on the amount of contamination and moisture entering the final fuel filter.
- It is important to drain accumulated moisture/water at least monthly from the final fuel
filter. Do not wait until the “Water In Fuel” indicator illuminates before performing this
maintenance.
- Maintenance on the final fuel filter / water separator is important. Follow the maintenance
schedule per ther Owners Manual. Replace the filter more frequently if highly
contaminated or high moisture content fuel is encountered.
- On a 5.9L engine, if the final fuel filter is replaced due to a high moisture content diesel
fuel, verify that the water sensor probes in the final filter have been cleaned. Excessive
moisture may contaminate the sensor sensing probes. The 6.7L engine includes a new
water-in-fuel sensor with the new final fuel filter element.
- The final fuel / water separator filter must meet or exceed OEM specifications. Some
aftermarket filters may not meet OEM specifications.
- The final fuel / water separator filter must meet or exceed the filtration specifications
listed in the table below.
