I'm not going to bore you with the whole thing but this involves the fuel filter and the TSB # is 14-007-06 and the filtering abilities of the filter for the 5.9L and the 6.7L engines.

here is the abridged version that I found:

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).
. . . . . . . .
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.
CATEGORY FUEL FILTER SPECIFICATION

- Final fuel / water separator filters that meet the above specifications are approved for use
on Cummins 5.9L and 6.7L diesel engines.
- The use of non-approved fuel filters will result in engine performance deterioration, and/or
possible progressive damage to the engine from foreign particle ingestion, and/or fuel
system component corrosion.
- It is recommended that customers use the MOPAR approved or Cummins Equivalent fuel
filters to protect the engine from debris and water contamination.

Damn Drew you are the MAN when it comes to filters huh?

That's some great info for those of you who have the 06 set up.

Nice job Drew !!

 

funny thing is this, I normaly dont touch the drain valve on my truck untill I change the filter, and I have yet to have ANY water in the catch pan

call me lucky, but I know as soon as I pull that filter out from my back seat I'll get water in the tank and be farked

 

I think if your getting your fuel from a place that has a high turnover rate, water shouldnt be a problem. I also havent seen any water come out of the drain. the place I get my diesel is a truck stop (just shut down for a month [:@] ) and goes thru a lot of diesel...

 

Even tho I have an '03, I switched to the 7u fuel filters as soon as they became available from Geno's.. and I will crack the valve (at the truck stop/gas station) probably every 3 or 4th tank (or more often if I am doubtful of where I HAD to buy fuel)..
