aFe DFS 780 Fuel Pumps
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.
