A new fuel filter
(12633243/TP3012) (Fig. 17) is now available for
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. It has been designed to offer
better protection in engines that may use an unreliable fuel source with
potential water conditions.
Compared to the existing dual
pleat design filter, the new coalescer filter provides the following
improvements:
-
Significantly improved
water separation with both diesel and biodiesel blended fuels to protect fuel
injectors and pumps from corrosion.
-
1.5 to 2 times the
contaminant capacity, depending on the type of contaminants in the fuel.
(Longer life/less prone to plugging problems and better performance at high
altitudes.)
-
Improved resistance to
cold weather plugging with diesel and biodiesel improperly blended or additized
for cold operation.
Please note that the new fuel
filter (12633243/TP3012) will be shipped in boxes labeled with a different part
number (98081884/TP3012) until the current inventory of boxes is exhausted.
For more information, refer
to ACDelco Bulletin #09D-068.
