Fits Dodge Diesel Trucks 2003–2004.5 with 5.9L Turbo Diesel

Part #: 42-22013

Overview

The aFe DFS780 Pro Fuel Pump is a high-performance, full-time operation fuel pump designed specifically for Dodge diesel trucks equipped with the 5.9L turbo diesel engine from 2003 to 2004.5. Crafted with precision engineering, this fuel pump ensures consistent fuel delivery, supporting your vehicle’s demanding performance needs. Whether you're upgrading for enhanced power, reliability, or durability, this pump provides a robust solution that helps maintain optimal engine operation under various driving conditions. Constructed from billet 6061-T6 aluminum, the manifold eliminates porosity concerns common with cast aluminum, ensuring long-lasting durability. The contoured CNC-machined passages optimize flow, reducing pressure drops caused by flow restrictions, which translates into more efficient fuel delivery. The heavy-duty carbon steel mounting bracket, supplied with hardware, offers secure and straightforward installation. Its marine-grade motor is protected against dust intrusion and powerful water jets, making it suitable for tough environments. Helical bronze spur gears are included, providing a forgiving operation even in contaminated conditions, enhancing the longevity and reliability of the pump.
