Diesel fuel can by dirty, filled with water, air vapor, and contaminants – all of which can wreak havoc on power and performance, as well as damaging your injectors. This aFe Power DFS780 is an auxiliary pump and filter for your 2011-2016 Duramax LML fuel system, working alongside your stock high-pressure transfer pump to improve throttle response and horsepower at all RPMs.
The DFS780 was designed from the beginning to eliminate weaknesses found in other “fuel transfer” system. aFe has spent almost four years engineering what we feel is the best, most reliable system available. Depending on the specific application, we offer features such as boost-activated fuel flow increase, a high-impact polycarbonate “sight glass” to visually check fuel conditions, a reliable “marine grade” motor and Viton seals to name a few.
Quick Features and Benefits:
- Clear high-impact polycarbonate sight glass allows visual inspection of fuel
- Helical bronze spur gear pump design runs quieter than straight cut gears
- IP56 Marine Grade (protected against dust intrusion and powerful water jets)
- Contoured CNC machining of manifold passages enhances flow to reduce pressure drop
- 1/8” NPT fuel pressure gauge port
- Viton seals which are compatible with most diesel and biodiesel fuels
- Typical installation time is two hours (plug and play – no modifications to fuel tank)
- Completely reversible – No damage to vehicle
- Built in the U.S.A.
FUEL FILTER WATER SEPARATOR
The DFS780 uses a high efficiency fuel filter that connects to a clear water separation bowl. While the fuel filter is removing contaminants, the water separation bowl allows for visual inspection of the collected water and provides ease of draining using the removable cap.
CLEAR SIGHT GLASS
A clear high-impact polycarbonate sight glass allows visual inspection of the fuel entering into the system.
