Description
Overview
The FASS Titanium Signature Series Plus Fuel System is the next evolution of the popular Titanium Signature Series, purpose-built to feed the 2017-2019 Chevrolet Silverado and GMC Sierra Duramax 6.6L. Engineered by FASS Fuel Systems to be a top-performing, long-lasting, and reliable aftermarket lift pump and filtration package, it delivers clean, air-free diesel to your engine while protecting the components that matter most. Rated at 140 gallons per hour and operating in the 70-75 psi range, it supports your Duramax from stock power all the way up to 500 HP.
What sets the Plus apart is a genuinely clean, professional installation. It comes equipped with ORB (O-Ring Boss) fittings, 6061 aluminum black anodized fittings, and black fuel line, giving the whole system a tidy, blacked-out look under the truck. The pump body is built from durable 6061 T-6 billet aluminum in a black finish for a rugged, cohesive appearance.
Advanced Filtration & Engine Protection
Duramax diesel engines are known for fuel-related injector failure issues, and FASS filtration is designed specifically to eliminate the ones caused by contaminated or aerated fuel. The Titanium Signature Series Plus combines an improved 2-micron filtration rating, a built-in water separation filter, and the patented FASS air/vapor removal process to help protect your injection system and injectors. By scrubbing out water, particulates, and entrained air, it effectively extends the service life of both your injection system and your injectors.
