The Racor PFF4245R2-02 ParFit Fuel Filter Head Assembly is a direct replacement for your 2004.5-2010 GM 6.6L Duramax LLY/LBZ/LMM. Over time, the seals in the factory filter head are known to leak causing issues such as hard starting, air leaks, and priming issues. Replacing the entire assembly eliminates the hassle of having to rebuild the unit. 

Racor is the OEM supplier to GM for this filter and assembly.

Will this work with my LB7?
View Staff Answer 

The RACOR PFF4245R2-02 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.)
