FASS Titanium Signature Series Diesel Fuel System 165GPH (8-10 PSI) for GM/Chevy Duramax 6.6L 2011-2014, 600-1,000HP Pro

Upgrading to a FASS Fuel System can greatly enhance your GM Duramax LML diesel engine, as it lacks a factory fuel system like other diesels. The Titanium Signature Series addresses this by reducing the stress on the CP3 injection system, which struggles to draw fuel under vacuum.

This top-performing, aftermarket system supports up to 165 gallons per hour and comes with a limited lifetime warranty, making it ideal for the Duramax 6.6L engine, especially for future fueling upgrades. Its advanced filtration features—such as a 2-micron rating, built-in water separation, and patented air/vapor removal—help protect and extend the life of injectors, mitigating common issues associated with injector failure.

With a failure rate of less than 2%, FASS Fuel Systems emphasizes quality and unique design features, establishing the Titanium Signature Series as a superior choice in the diesel industry.
