The diesel fuel in your truck contains contaminants, water, and air/vapor which is reducing power and damaging your diesel fuel injectors. Introducing the aFe POWER DFS780 Diesel Fuel System, with its patent-pending design capable of removing power-robbing entrained air, water and contaminants. The DFS780 also boosts fuel pressure ensuring constant availability for the high-pressure transfer 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.
