aFe DFS780 Boost Activated Fuel Pump

The aFe DFS780 Boost Activated Fuel Pump is a diesel electric lift pump and fuel system upgrade. It is designed to give the high-pressure injection pump a steady supply of fuel when the engine is under load. The pump works with the factory fuel system. It helps remove air, water and other contaminants from the fuel, and it supports throttle response and power across the RPM range.

Key Features:

• Boost-activated engagement: a supplied boost switch turns the pump on under load. This reduces wear on the DFS780 and on the stock lift pump.
• Clear high-impact polycarbonate sight glass: lets you check the fuel visually.
• Helical spur gears: run quieter than straight-cut gears. They ride on PEEK bearing surfaces to reduce noise and wear.
• Contoured CNC-machined billet aluminum manifold: improves flow and reduces pressure drop.
• "Marine grade" motor: protected against dust and water.
• Fuel pressure gauge port: lets you attach an external gauge to monitor fuel pressure.
• O.E.-quality Viton seals: resist fuel exposure.
• Plug-and-play installation: the supplied harness uses Deutsch weather-proof connectors, and the stock fuel lines do not need to be cut or modified.

Built in the U.S.A. by aFe Power, the DFS780 is a good fit for diesel truck owners who tow, haul or run performance upgrades and want more fuel supply. The pump is part-time, so the factory pump handles light-load driving.
