aFe DFS780 Fuel Pump
2005–2010 Dodge Ram 2500 / Ram 3500
42-12032
Overview:
The aFe DFS780 Fuel Pump is a high-performance diesel fuel system designed specifically for 2005 to 2010 Dodge Ram 2500 and Ram 3500 trucks. This advanced fuel system addresses common issues found in diesel fuel delivery, such as contaminants, water, and entrained air that reduce engine power and damage fuel injectors. By removing these harmful elements and boosting fuel pressure, the DFS780 ensures consistent fuel availability to the high-pressure transfer pump, resulting in improved throttle response and horsepower across all RPM ranges.
Engineered with nearly four years of development, the DFS780 offers a reliable and efficient solution for diesel truck owners seeking enhanced performance and durability. Its boost-activated fuel flow feature adapts to engine demands, making it an ideal upgrade for those who want to maximize their truck’s power and reliability under various driving conditions.
Key Features:
The aFe DFS780 Fuel Pump incorporates several innovative features that set it apart from conventional fuel transfer systems:
- Clear high-impact polycarbonate sight glass for easy visual inspection of fuel conditions
- Helical spur gears that operate quieter and more efficiently than straight-cut gears
- Marine-grade motor construction providing superior protection against dust and water intrusion
- Contoured CNC-machined manifold designed to enhance fuel flow and reduce restrictions
- Fuel pressure gauge port for convenient monitoring of fuel system performance
- OE-quality Viton seals ensuring long-lasting durability and resistance to fuel contaminants
- Boost-activated fuel flow increase to meet higher engine demands under boost conditions
- Built in the U.S.A. with stringent quality control standards
Construction & Design:
The DFS780 is crafted with premium materials and precision engineering to withstand the harsh conditions of diesel fuel systems. The high-impact polycarbonate sight glass allows users to monitor fuel quality without disassembly, while the marine-grade motor ensures reliable operation even in dusty or wet environments. The use of Viton seals provides excellent chemical resistance, preventing leaks and degradation over time. Additionally, the CNC-machined manifold is contoured to optimize fuel flow, reducing turbulence and pressure drops for consistent delivery to the engine.
Performance & Sound
By removing entrained air, water, and contaminants from the diesel fuel, the DFS780 improves combustion efficiency and protects sensitive fuel injectors from damage. The boost-activated fuel flow feature ensures that the engine receives adequate fuel pressure during high-demand situations, enhancing throttle response and horsepower throughout the RPM range. The helical spur gears contribute to quieter operation compared to traditional gear designs, resulting in a smoother and more refined fuel pump sound.
Installation & Fitment:
The aFe DFS780 Fuel Pump is designed for direct fitment on 2005–2010 Dodge Ram 2500 and Ram 3500 diesel trucks. Installation typically takes around two hours and requires no major modifications, making it accessible for experienced DIY enthusiasts or professional installers. The system integrates seamlessly with the existing fuel setup, providing an immediate upgrade in fuel delivery performance and reliability.
