ROI Series | 2011-2016 Chevrolet/GMC with 6.6 Duramax

January 21, 2025

If you’ve ever wondered about the return on investment (ROI) of a FASS Fuel System, this is the video series for you! In our ROI Video series, we’re discussing the science behind FASS, and how we’re able to save our customers (in many cases) thousands of dollars.

In the coming weeks, we’ll cover the various engines and platforms we fuel system and filtration upgrades for—starting with 2011-2016 GM trucks powered by the 6.6 liter LML Duramax.

Please note: MPG improvements depend highly on the owner’s driving habits, record-keeping methods, fuel quality, and more. While observing increased fuel economy is extremely common after installing a FASS Fuel System, we cannot guarantee a measurable MPG improvement.

We’re proud to be a family-owned, U.S.-based manufacturer. From our production facility in Marthasville, Missouri, we serve diesel owners around the world.
