      Description

      Fueling the Beast. The AFE DFS780 Fuel System is engineered to replace the factory lift pump, delivering consistent fuel pressure to your CP3 injection pump. Its patent-pending design removes entrained air, water, and contaminants, enhancing throttle response and horsepower across all RPMs. With the capacity to support fuel flow for over 2000 HP, this AFE DFS780 Fuel System ensures your engine receives the clean, uninterrupted fuel it demands.

      Built Tough. Constructed with billet 6061-T6 aluminum, the AFE DFS780 Fuel System's manifold eliminates porosity concerns associated with cast aluminum. Helical bronze spur gears, more forgiving of contaminants than steel, run quieter than straight-cut gears. PEEK (Polyether Ether Ketone) bearing surfaces further reduce noise and wear, ensuring long-term reliability.

      Installation. Putting this AFE DFS780 Fuel System; Full-Time Operation on your 5.9L RAM 2500 takes 2 hours to install.

      Warranty. There is a limited warranty on this product.

      Application. The AFE DFS780 Fuel System; Full-Time Operation fits 2003-2004 5.9L RAM 2500 models.
