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
