Titanium Signature Series 165 GPH Lift Pump

The FASS Titanium Signature Series 165 GPH lift pump is designed to enhance performance, longevity, and reliability for 2001-2010 GM 6.6L Duramax (LB7, LLY, LBZ, LMM) engines. This system actively removes harmful fuel contaminants such as water, air, and debris, contributing to increased horsepower and fuel economy. By ensuring a cleaner fuel supply, it also lowers maintenance costs, reduces emissions, and extends the lifespan of critical components like the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system, ultimately leading to improved miles per gallon and a more efficient combustion event. Engineered with FASS Whisper Technology, this pump operates quietly without compromising flow rates. Its aluminum housing features performance radius cuts for smooth fuel flow, and the mass flow return system continuously polishes the fuel and prevents cavitation. The pump is preset at 8-10 PSI and supports 600 to 900 horsepower. For applications nearing 550-600 horsepower, FASS recommends their Bulkhead and Suction Tube kit (STK1002) for a larger fuel volume retrieval and convenient return option, crucial for high-performance Duramax setups. Duramax engines, unlike many other diesel platforms, lack a factory lift pump, forcing the CP3 or CP4 injection pump to draw fuel under vacuum. This can stress the injection pump and introduce air into the fuel system, which is a common cause of injector failure. The FASS Titanium Signature Series addresses this by providing a robust lift pump and filtration system that protects against fuel-related injector issues and extends the life of your injection pump and injectors.
