Overview
Overview
Full-Time Diesel Fuel System (42-14021) by aFe. 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.
aFe (Advanced Flow Engineering, Inc.) manufactures performance products for late model cars, light trucks and SUVs. The company was founded in 1999 with an initial concentration on high performance air filters. Since then, the company product line has broadened to include cold air intakes, fluid filters, exhaust systems, intake manifolds, intercoolers, programmers, differential covers, transmission pans and throttle body spacers. The team of engineers, machinists, production and sales people at aFe have many years of experience in their respective positions, and together work to ensure they produce the best automotive products on the market.
