Titanium Signature Series 165 GPH Lift Pump

The FASS Titanium Signature Series TSC10165G is a 165 GPH lift pump meticulously engineered for exceptional performance, longevity, and reliability in Duramax diesel engines. This fuel system actively removes potentially harmful and destructive fuel contaminants such as water, air, and general debris, contributing to increased horsepower and improved fuel economy while lowering maintenance costs and emissions. The advanced filtration provided by FASS systems helps protect your Duramax’s injection systems, effectively extending the life of your Injection Pump and Injectors and reducing injector failure issues. Featuring FASS Whisper Technology, this pump reduces noise levels without sacrificing flow rates. The aluminum housing includes performance radius cuts for smooth fuel flow, and the mass flow return continuously polishes your fuel, preventing cavitation. This lift pump supports between 600 to 900 horsepower and is preset at 8-10 PSI fuel pressure. This lift pump is specifically designed to fit 2001-2010 GM 6.6L Duramax LB7, LLY, LBZ & LMM engines. FASS recommends upgrading to their Bulkhead and Suction Tube kit (part number STK1002) if you are close to 550 to 600 horsepower, as this allows for a larger volume of diesel fuel to be retrieved and offers a convenient return option, crucial for high-performance applications demanding significant fuel volume. FASS Titanium fuel systems are a vital upgrade for Duramax diesels, which lack a factory lift pump, thereby preventing the injection pump from pulling fuel under a vacuum. This vacuum condition can stress the injection pump and introduce air into the fuel.
