#04-06-04-070B: Information on Improved Fuel Filter for 6.6L Duramax Diesel Engine - (Mar 2, 2009)
Subject:
Information on Improved Fuel Filter for 6.6L Duramax™ Diesel Engine
Models: 2001-2009 Chevrolet Silverado
2003-2009 Chevrolet Kodiak
2006-2009 Chevrolet Express
2001-2009 GMC Sierra
2003-2009 GMC TopKick
2006-2009 GMC Sierra
Equipped with 6.6L Duramax™ Diesel Engine (VINs 1, 2, D, 6 - RPOs LB7, LLY, LBZ, LMM)
________________________________________
This bulletin is being revised to provide additional information to the field on fuel filter applications for the Duramax™ diesel engine. Please discard Corporate Bulletin Number 04-06-04-070A (Section 06 - Engine/Propulsion System).
________________________________________
Important: It is acceptable to use diesel fuel containing up to 5% biodiesel (B5). Higher concentration (i.e., greater than B5) biodiesel-containing fuels or the use of unmodified bio-oils blended into diesel fuel at any concentration is not recommended and could damage the fuel system and engine. Such damage would not be covered by your warranty.
A revised fuel filter is released that will service all 2001-2009 Chevrolet and GMC C/K models and 2003-2009 Chevrolet and GMC C4500/5500 Series vehicles with the 6.6L Duramax™ Diesel. The new coalescer filter provides the following benefits / improvements over the existing dual pleat design:
• 150-200% increase in service life, depending on contaminant type
• Improved fuel system protection with some premium diesel and B5 biodiesel blends
• Equivalent coarse water droplet removal efficiency of previous design
• Greatly improved removal of emulsified water - a major contributor to fuel system issues
Proper fuel filter servicing and the use of clean diesel fuel that is free of water or contaminants are critical for the longevity of fuel system components of a modern direct injected diesel engine. Adherence to the fuel filter change interval will help to ensure that the Duramax fuel system will be protected from contaminants and that the engine will continue to operate as designed. Purchasing fuel from a high volume fuel retailer increases the chances that the fuel is fresh and of good quality.

I cured this problem recently... I bought my wife her own Dmax... now she can leave mine alone...
I went through injectors a lot in the first couple years, following the service guide... then I started using a better filter system, and changing them often... I've had the same injectors for a while now, and the truck has 256K on it...
