Make Your Duramax Run Like It Was Built To

If you’re pushing serious power or towing heavy with your 2001–2010 Duramax, your fuel system needs more than what GM gave it from the factory. The FASS TSC10165G Titanium Signature Series 165GPH Lift Pump is built to support hard-working and high-horsepower trucks that demand more fuel, more consistency, and better protection. It takes the load off your CP3 or CP4 by supplying constant fuel pressure and removing the air, vapor, and contaminants that can quietly destroy injectors over time. You’ll feel the difference in smoother idle, faster throttle response, and more reliable performance when your truck is under load. Whether you’ve upgraded your injectors, added a turbo, or just want to avoid pressure drops at wide open throttle, this system keeps up without breaking a sweat. It’s quiet, durable, and built to handle 600 to 900 horsepower without sacrificing drivability. If you’re investing in power, this is the fuel system that keeps your Duramax running clean and strong.

Built To Fuel High Performance Without Compromise

The FASS 165GPH Titanium Signature Series is engineered specifically for 2001–2010 Duramax LB7, LLY, LBZ, and LMM engines that see higher horsepower, heavy towing, or frequent load demands. It flows 165 gallons per hour at a consistent 8 to 10 PSI, delivering more volume than the 100GPH model to support modified fuel systems and higher output builds. Key features include a 2-micron particulate filter and an Extreme Series water separator, which work together to keep the fuel clean and protect precision components. Mass Flow Return technology recirculates excess fuel through the filters, so only freshly polished fuel reaches the injection pump. Performance Radius Cuts inside the pump eliminate turbulence and reduce aeration, which helps maintain steady pressure under throttle. FASS Whisper Technology keeps pump noise to a minimum, even with the higher flow rate. The system installs using bolt-on brackets at factory mounting points, and includes all wiring and hardware needed to get it done right. For serious Duramax builds, this pump is a long-term solution built to perform under pressure.
