Master Filter Head Kit, Duramax | 2001 - 2010 - Merchant Automotive - 10320

Replacing the fuel filter head on a Duramax engine can be a daunting task as there are a few different parts you will need to replace to complete the job. The fuel filter head mounts the fuel filter, acts as the primer for the supply-side of the fuel system, and houses the fuel heater to aid in cold-weather operation. This poses many different points of possible failure when it comes to the fuel filter head.
