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.
Merchant Automotive has developed an all in one Duramax fuel filter head kit to replace all of the most common wear items on your fuel filter head. In this kit you will receive a complete filter head rebuild kit, an MA aluminum bleeder screw to upgrade your factory plastic screw, a water in fuel plug, an OEM replacement fuel filter and a bottle of MA additive to finish up your install. This kit is great for rebuilding a failed fuel filter head or to use as a maintenance/upgrade kit for preventative maintenance.
