2001-2016 Duramax Dirty Diesel Cat Fuel Filter Adapter (DUR-FUE-A046)
Built right here in-house we're happy to offer this high-quality machined CAT fuel filter adapter for your Duramax! This adapter replaces the factory filter and housing with a CNC machined, billet aluminum housing that takes a CAT, 2-micron filter that is readily available at a low cost to make sure you can keep clean fuel feeding that powerhouse of a Duramax.
- Machined from billet aluminum for a precise and reliable fit
- Includes required hardware and filter head spacer
- Central adapter designed to eliminate leak path through threads that is present on other adapters
- Fuel-rated O-Rings for a leak-free install
- Accepts various aftermarket filters, such as the popular CAT 1R-0750 filter *not included* so you can run exactly the filter you want.
- Cat 175-2949 fuel/water separator will also thread on to use this as a downstream separator with an aftermarket lift pump.
CAT Filter Sold Separately. This does require the removal of the factory water in the fuel sensor. This will not throw any sort of check engine light codes.
