FASS TSC12165G Titanium Signature Series 165GPH Diesel Fuel Lift Pump System

The FASS TSC12165G Titanium Signature Series is an advanced diesel fuel lift pump and air separation system engineered specifically for 2015-2016 GM Duramax LML 6.6L engines. This system addresses a critical weakness in the Duramax design—the lack of a factory lift pump—which forces the CP4 injection pump to pull fuel under vacuum, adding stress and introducing air that can lead to premature failure.

Key Features:

• 165 gallons per hour flow rate at 8-10 PSI, supporting 600-900 horsepower applications
• 2-micron filtration rating with integrated water separation for maximum injection system protection
• Patented air and vapor removal process eliminates harmful contaminants before they reach injectors
• FASS Whisper Technology drastically reduces pump noise while maintaining high flow rates
• Performance Radius Cuts (PRC) within aluminum housing prevent air reintroduction and fuel stagnation
• Mass Flow Return (MFR) technology continuously polishes fuel by circulating it through the filtration system
• Bolt-on steel mounting brackets utilize factory bed bolts for quick, drill-free installation
• Limited lifetime warranty coverage

This complete system includes all necessary mounting hardware, brackets, and plumbing. The Titanium Signature Series protects your expensive CP4 injection pump and injectors by ensuring consistent fuel pressure, removing damaging air and water, and filtering particles down to 2 microns—far superior to factory filtration.
