Give Your Duramax The Fuel System It Deserves

If you own a 2001–2010 GM 2500HD or 3500HD with a Duramax engine, there's a good chance your truck is still relying on the injection pump to pull fuel on its own. The problem is, GM never gave these trucks a factory lift pump, which means your CP3 or CP4 is working harder than it should. That extra strain invites air, vapor, and debris into the fuel system, which over time, can lead to expensive injector and pump failures. The FASS TSC10100G Titanium Signature Series takes that burden off your fuel system by supplying a constant, pressurized stream of clean diesel directly to the injection pump. It doesn't just move fuel, it filters it down to 2 microns, removes water, and strips out air before it ever reaches the engine. You’ll notice a smoother idle, sharper throttle response, and improved performance, especially under load. Whether you're towing heavy, daily driving, or running mild performance upgrades, this lift pump gives your Duramax the support it should have had from the factory. Plus, it's backed by a Lifetime Warranty when registered, giving you serious peace of mind with every mile.

Built For Clean Reliable Fuel Delivery Every Time

The FASS Titanium Signature Series TSC10100G is a complete fuel delivery and filtration upgrade designed specifically for 2001–2010 Duramax LB7, LLY, LBZ, and LMM engines. It flows 100 gallons per hour at a steady 8 to 10 PSI, which is perfect for stock and moderately tuned trucks making up to 600 horsepower. One of the standout features is FASS’s Mass Flow Return system, which continuously cycles fuel through the filters to maintain maximum cleanliness and eliminate trapped air. It also uses Performance Radius Cuts inside the pump housing to prevent turbulence and dead spots that could reintroduce aeration. A 2-micron particulate filter and an Extreme Series water separator come standard, delivering far superior filtration compared to OEM setups. Built with Whisper Technology, this pump operates quietly enough to blend right into modern diesel cabins. Installation is straightforward thanks to a bolt-on bracket system that uses factory mounting points, and the included wiring harness makes setup clean and efficient. With CARB approval and a design tailored to long-term durability, it’s one of the most trusted solutions for protecting your injectors and maintaining consistent fuel pressure on the Duramax platform.
