Product Description

The FASS TSC11165G Titanium Signature Series 165 GPH Fuel System is engineered specifically for 2011-2014 Chevrolet Silverado and GMC Sierra 2500/3500 trucks equipped with the 6.6L LML Duramax diesel engine. This premium fuel system delivers a robust 165 gallons per hour at approximately 8-10 PSI of fuel pressure, helping reduce the vacuum pull on the factory CP3 injection pump and improve overall fuel delivery reliability. Its advanced air/vapor separation and 2-micron absolute filtration help protect injectors and key fuel system components by removing water, air, and contaminants before they reach critical areas of the engine.

Built with Whisper Technology to minimize operational noise and engineered with Performance Radius Cuts and Mass Flow Return for smoother, more efficient fuel flow, the TSC11165G supports moderate to high-demand applications in the ~600-1000 HP range. Optional heater and fuel pressure gauge ports add flexibility for cold-weather performance and monitoring, while bolt-on mounting brackets and comprehensive hardware make installation straightforward for experienced DIYers or professional installers. This system provides a durable, high-performance fueling solution for LML Duramax owners seeking enhanced fuel cleanliness and delivery over stock setups.
