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.
