Good To Know

Q: Does this housing include a new fuel filter element? A: No, the housing is sold alone; you will reuse the existing filter cartridge or buy one separately.

Q: Will it fit a 2003 GMC Sierra 2500 HD with the Duramax? A: Yes, it fits all 2001–2016 Duramax LLY, LBZ, LMM, and LML engines, but always check your build date and OEM part number for certainty.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
