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
