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.

14-007-06 -2-

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.

The big question I have is this: why wouldn't this apply to 5. 9L CTD's 2004. 5 - 2005? It's the same engine...

 

[DCarner]

You guys aren't as cool... ...

 

[Smokin Joes 2500]

You guys aren't as cool... ...

THATS RIGHT... ... WERE COOLER :-laf :-laf :-laf :-laf :-laf

 

[nickleinonen]

and i got a bunch of fs19579 fuel filters coming my way... oh well. . also have some ff5319/20 2u filters coming too

 

[RobertP]

see i still think that there is one problem. the filters listed above are only 7 micron. i have one in my truck. but still bosch recommends a 2 micron for the CR design with these injectors. why hasn't dodge step up to the plate and just put in 2 micron filters.



p. s. im not bashing the company, seeing how i do work at a dealership.



actually we have a diesel in now with a fuel system problem and after seeing how much water is in his tank and fuel system i was amazed. the injector tubes had rust all over them. i can only imagine what the inside of the cp3 and injectors look like.



also after messing with this truck in the shop i have found that even if you drain the filter housing you still dont get the water out if parked on flat ground. still a good 1/4 inch in the canister. is what i have noticed in this truck.

Robert,

That would mean that Dodge would have to use a "real" electric fuel pump to push or pull thru that 2 micron.

 

[RobertP]

that would save the alot of headache and money thou.

 

[JThiessen]

So I wonder what changed after March of '06 and prior vehicles? I'd think that this Information would apply to all Common Rails.

 

[WDimig]

i guess dodge is just going to leave it up to the educated conusmers to put the right filtering system on thier trucks , and then when something happens to thier trucks, the aftermarket items now pose a warranty threat. oh well, glad i got a 12V that doesent really give a hoot whats run in it!... . well almost.

I'm getting closer and closer to buying a chevy. All the BS that D/C is putting people through is rediculous. I can't believe that as good of a rep as Cummins has that their gonna let D/C ruin it for them. I know more and more people going to Chevys because of D/C being the way they are. I wish GM would get the engine instead of Dodge really. Until the 3rd gens, The Dodge truck was really crap anyway, besides the engine. I've had several that when you mash the brake, it tries to put you in the ditch. I've got a 1977 chevy 4wd that drives way better than my last 2nd gen. Anyway, enough venting. But I did get SMOKED by a 2006 chevy yesterday. It got crazy every time it shifted. That allison must shift firm.

 

[DPKetchum]

G. M. has/had a recall on their fuel filters. I've been trying to find out the micron rating of the OLD and their RECALL filter. Stopped at a Chevy store. Tech said he does injector replacement weekly. NONE of the info he had on the filters(including the recall filters)list a micron rating. Anyone got a clue?

 

[Diesel Power]

on a gm you only have a cp3 to pull fuel through the filters, now they go to a better filtering filter---good for a stock truck. but once you mod it you now have a restriction, the more power you try to get the more the cp3 is working and being restricted, it has no pusher pump. that condition puts in air in the fuel and causes fuel starvation in the cp3 and the injectors, which is there #1 source for lubrication----thats why they are still failing, the chevy needs a pusher pump Oo.

 

[DPKetchum]

But what is the MICRON rating of the NEW filter used on them. I inquired about a pusher pump etc. Tech said only a new updated filter. Curious to the micron rating of it. I posred it on a G. M. site 48 hours ago with over 50 lookers as of last night with no replys.

 

[Yo Hoot]

GM's are injector eaters and the first two model years are starting to show headgasket weakness. This fellows, is a bad sign for the follow-on years as they haven't done anything to the headgasket design.



GM makes a BIC lighter diesel. :-laf



I find this TSB to be no different than the requirements of all of the diesel brands so what's the problem?

 

[Buffalo]

Recently, GM came out with a dual-element fuel filter for the Duramaxes. I believe it has 7 & 5 micron ratings.



The Duramax guys have been addressing finer fuel filtration for quite awhile, now. There is a guy at the Duramax website building fuel filtration systems utilizing Caterpillar High Efficiency filters that filter to the 2 micron level. In fact, I installed one for my 115 gal. in-bed aux. fuel tank, over a year ago. Learned about that filter from the Duramax filter guy.

[DPKetchum]

I saw the recall filter. Yes its got EXTRA added t the bottom of it. Is it a 7 and 5 or is that a gues estimate number.

"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"
