Description
Overview
The Titanium Signature Series Plus Fuel System from FASS is purpose-built for 2015-2016 Chevrolet Silverado and GMC Sierra trucks powered by the 6.6L Duramax diesel. Engineered as the next evolution of the popular Titanium Signature Series, the Plus variant elevates both performance and presentation, giving your Duramax a fuel delivery solution designed to be the top-performing, longest-lasting, and most reliable aftermarket filtration system in the diesel industry.
Built around a 6061 T-6 billet aluminum housing finished in black, this system is rated to support up to 600 horsepower with a fuel delivery rate of 100 gallons per hour, giving stock and mildly modified Duramax owners the fuel volume needed for consistent, reliable performance. Every unit is sold each, so you get a complete, dedicated fuel system engineered specifically for your truck’s fuel demands.
What Makes the Plus Series Different
The Titanium Signature Series Plus distinguishes itself with ORB (O-Ring Boss) fittings, black anodized 6061 aluminum fittings, and matching black fuel line, delivering an ultra-clean, finished installation under the hood. Beyond the visual upgrade, these fittings provide a more secure, leak-resistant seal compared to standard fittings, which matters when you’re running a high-flow fuel system day in and day out.
Filtration & Engine Protection
At the core of the Titanium Signature Series Plus is advanced filtration engineered to protect your Duramax’s injection system and injectors. A 2-micron filtration rating captures fine contaminants before they reach sensitive fuel system components, while a built-in water separation filter keeps damaging moisture out of your fuel. FASS’s patented air/vapor removal process further protects against the fuel aeration issues that contribute to injector wear and premature failure — a known weak point for Duramax engines. By addressing fuel-related causes of injector failure, this system is designed to help extend the service life of both your injectors and your entire injection system.

This fuel system is designed specifically to fit 2015-2016 Duramax 6.6L trucks and SUVs, ensuring proper integration with your factory fuel system architecture.
