aFe Power DFS780 Pro Fuel System (Full Operation) | 2001-2016 6.6L GM Duramax

Introducing the aFe POWER DFS780 Pro Full Operation Fuel System for the 2001-2016 6.6L GM Duramax, with its patent-pending design capable of removing power-robbing debris such as air, water and other contaminants. The DFS780 Pro also boosts fuel pressure ensuring constant availability for the high-pressure pump, improving throttle response and horsepower at all RPMs.

The DFS780 was designed from the beginning to eliminate weaknesses found in other "fuel transfer" system. aFe has spent almost four years engineering what we feel is the best, most reliable system available. Depending on the specific application, we offer features such as boost-activated fuel flow increase, a high-impact polycarbonate "sight glass" to visually check fuel conditions, a reliable "marine grade" motor and Viton seals to name a few.
