Protect Your LML With The Fuel System It Deserves

If you own a 2011–2014 LML Duramax, you already know how capable the truck is, but you may also know the CP4 pump has a reputation for failing without much warning. That pump struggles when it sees aerated fuel or pressure drops, which is why installing the FASS TSC11165G Titanium Signature Series Lift Pump is one of the smartest upgrades you can make. This system provides a steady supply of clean, pressurized fuel, giving your injection pump the support it needs to stay healthy under any kind of load. It removes air and vapor that the factory setup can’t manage, and that alone helps the truck run smoother and respond quicker when you get on the throttle. The added filtration and water separation protect your injectors, which can save thousands of dollars in repairs down the road. Many LML owners install this pump for peace of mind, especially if they tow or run performance tuning. It is a reliable way to take control of your fuel system before problems ever start.

Engineered To Stabilize Fuel Delivery For Every LML Application

The FASS TSC11165G Titanium Signature Series 165GPH system is built specifically to address the weaknesses of the 2011–2014 LML Duramax fuel system. It delivers 165 gallons per hour at a consistent 8 to 10 PSI, which keeps the CP4 pump supplied with positive pressure instead of the vacuum conditions created by the stock setup. The system uses a 2 micron particulate filter and a high efficiency water separator to remove the contaminants and moisture that often contribute to CP4 wear. Its Mass Flow Return design continuously recirculates fuel through the filters so the engine receives polished fuel every time you drive. Performance Radius Cuts inside the pump eliminate turbulence that could reintroduce air, keeping the fuel completely stable even when the truck is under heavy throttle. FASS Whisper Technology helps the system operate quietly, making it blend in seamlessly with the truck despite the higher flow capacity. With bolt on brackets, included wiring, and a Lifetime Warranty when registered, this lift pump provides a complete and dependable solution for anyone who relies on their LML.
