I called Cummins Technical Service and they told me my 06' came with a 10 micron from the dealer. Now Cummins recommends the 7 micron by Fleetguard.

Hounddog

He said 5 micron to absolute.

Pooter

No one makes a 5 micron for the stock filter housing.

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.

Sounds like he doesn't know what he is talking about... and he was the SM!

cougaram

It appears that the 7 micron filter only applies to engines built after March 2006 according to the TSB.

Hounddog

After being told by Bosch that they would not give out the recommended micron rating(had e/mailed them) I didn't pry when on Friday late in the day a guy from Bosch R&D called and spit out the 5 micron to absolute.The message I left the day before on a answering machine was that I was installing a twin diesel set up in a boat with HPCR systems and needed to know the recommended micron rating for their(Bosch) HPCR system.He did say ALL our HPCR systems before he said the 5 micron deal.

Spooler

That's funny!!!!!!!! Beat the info out of them any way you can.....

Hounddog

Made me wonder if the reason Bosch corperate said it was PROPRIETARY is because of Dodge and Duramax trucks as their system is used on however many have been produced and sold over the years compared to boats,generators,locomotive engines etc.Seems like a small fact to make it a guarded secret.

Mr Bee

I stopped by my local cummings dealer yesterday and he called fleetguard
and 7 is all that they produce for our trucks.
If there is a 5 Micron, If a ******* is telling you that, surely they should have them in stock? It's all about put up a part number.

Pooter

Where is your local Cummings dealer?

I only have Cummins down here in Texas.

Lightman

Hounddog, not to pick at the wording you've been using, but there is no such thing terminology wise as 'xx-micron to absolute' . Filters are given a rating that denotes their efficiency at a certain size of particle removal, typically for one pass. These ratings are either 'absolute' or 'nominal' . Typically when someone says a 5 micron absolute, what it means is that the filter on one pass will remove 95%+ of the particles in that 5 micron size range. Nominal means something like 70%, I'm not sure of the exact cutoff. Just wanted to clarify, 'to absolute' doesn't mean down to a certain or 0 micron range..

subspd

Like I said he doesn't know what he is talking about he said to use a 5 micron filter only but then gave me the part number for a 7 micron filter??? Strange...

03 ant a hemi

What has most likely happend is that although the 7micron filter will filter down to the 7 mics @98.9% or so. It more then likely has a secondary rating of 5 microns @80% or something like that.
Confusion can, has and still will arise with filtration and true filtering abilities.

bluebull

If you take what you said and lightman said that could absolutely be what's going on.
