Overview
The FASS Titanium Signature Series Plus is the next evolution of the popular Titanium Signature Series Fuel System, engineered specifically for the 2011-2014 Chevrolet Silverado and GMC Sierra Duramax 6.6L. Designed to be a top-performing, long-lasting, and reliable aftermarket filtration and fuel delivery solution, this dedicated fuel system draws clean, air-free diesel to your engine while protecting the components that keep your truck running strong. Rated at 100 gallons per hour, it supports your Duramax 6.6L with enough fuel for builds up to 600 HP.
Key Benefits
Duramax diesel engines are well known for injector failure issues, and FASS filtration systems are designed to eliminate the failures that are fuel-related. The Titanium Signature Series Plus delivers advanced filtration that helps protect your injection system, effectively extending the life of both the injection system and the injectors. An improved 2-micron filtration rating, a built-in water separation filter, and the patented FASS air/vapor removal process work together to send cleaner, drier, more consistent fuel to your engine.
What sets the “Plus” apart is the attention to a cleaner, more refined installation. It is equipped with ORB (O-Ring Boss) fittings, 6061 aluminum black anodized fittings, and black fuel line for an ultra-clean, finished look under the truck. Machined from 6061 T-6 billet aluminum and finished in black, this system is built for durability and a professional presentation.
