Don't cheap out and buy aftermarket. This OEM is the only way to go.
Rick (Va) | July 4th, 2022
Fits perfect just what truck need
Kelvin (California) | June 27th, 2022
I checked the forums and the recommendation was to buy the OE filter head from XDP. The part was a perfect fit for our 2007 Classic LBZ, hoses fit as original.

Questions and Answers
Will this work with my LB7?
View Staff Answer
Answer
The GM 12642623 is a direct fit for 2004.5-2010 GM 6.6L Duramax 6.6L.
That being said, the Fuel Filter Head Assembly can be used on LB7 applications. This requires additional fuel line and rerouting to work properly. (You will not have the ability to reconnect the filter head heater wires. This will not cause any CEL’s or issues.)
