Description
Overview
The FASS Titanium Signature Series Plus Fuel System is the next evolution of the popular Titanium Signature Series, purpose-built for the 2001-2010 Chevrolet Silverado and GMC Sierra Duramax 6.6L. Engineered by FASS Fuel Systems to be a top-performing, long-lasting, and reliable aftermarket filtration and lift pump solution, it delivers a steady 8-10 psi and is rated at 290 gallons per hour — enough fuel to support your Duramax 6.6L diesel engine on builds up to 1500 HP.
What sets the Plus apart is a refined, ultra-clean installation. It comes equipped with ORB (O-Ring Boss) fittings, 6061 aluminum black anodized fittings, and black fuel line, giving the entire setup a stealthy, finished look under the truck. The pump body is machined from durable 6061 T-6 billet aluminum and finished in black, so it looks as purposeful as it performs.
Advanced Filtration & Injector Protection
Duramax diesel engines are well known for fuel-related injector failure issues, and FASS filtration systems are specifically designed to eliminate those problems at the source. The Titanium Signature Series Plus provides advanced filtration that helps protect your injection system and effectively extends the life of both your injection system and your injectors. It achieves this through an improved 2-micron filtration rating, a built-in water separation filter, and the FASS patented air/vapor removal process that strips damaging air and vapor from your diesel fuel before it reaches the engine.
