The aFe DFS780 Full-Time Operation Fuel Pump is a high-performance diesel fuel system designed specifically for GM 6.6L V8 L5P engines from 2017 onwards. This system features a patent-pending design that actively removes contaminants, water, and air/vapor from the diesel fuel, which are common sources of power loss and injector damage. By eliminating these impurities, the DFS780 enhances fuel quality and consistency, leading to improved throttle response, increased horsepower, and more reliable engine operation. Constructed with durable materials suitable for demanding diesel applications, this fuel system ensures long-lasting performance and optimal fuel delivery under various driving conditions.

Designed for 2017 and newer GM trucks equipped with the 6.6L V8 L5P diesel engine, the DFS780 serves as a direct replacement and upgrade for the factory fuel system. It actively maintains constant fuel pressure to the high-pressure transfer pump, supporting high-performance and heavy-duty use cases such as towing, off-road driving, and daily driving. The system is engineered for full-time operation, continuously filtering out harmful contaminants and water, which helps protect your injectors and improve overall engine efficiency. Installation involves replacing the existing fuel system components, and the kit includes all necessary parts for a straightforward upgrade, making it suitable for both professional and DIY enthusiasts seeking enhanced diesel fuel management.

Overview

Full-Time Diesel Fuel System (42-14023) 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.
