Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.

aFe DFS 780 fuel pumps are powered by your stock ignition and can be run independently or in parallel with the factory fuel pump. They feature helical bronze spur gears that are more forgiving of contaminants than steel gears and they run quieter than normal straight-cut gears. The billet aluminum manifold holds the fuel pump and houses the clear high-impact polycarbonate sight glass for visual inspection of fuel. These fuel pumps are supplied with a plug-and-play wiring harness with Deutsch weather-proof connectors; no cutting or modification is required for installation. High-quality Viton® seals are used, making them compatible with both diesel and biodiesel fuels.
