Description
Overview
The FASS Titanium Signature Series Plus is the next evolution of the popular Titanium Signature Series Fuel System, engineered specifically for the 1989-1993 Dodge Cummins 5.9L. Built as a dedicated lift pump and filtration system, it delivers clean, air-free fuel to your injection system while giving your engine bay an ultra-clean, factory-plus finish. Rated at 100 gallons per hour, this system supports your Dodge RAM Cummins 5.9L diesel from stock output all the way up to 600 horsepower.
Key Benefits
Cummins diesel engines are well known for fuel-related injector failure issues, and FASS filtration systems are designed to eliminate those problems. The Titanium Signature Series Plus combines an improved 2-micron filtration rating, a built-in water separation filter, and FASS’s patented air/vapor removal process to protect your injection system and injectors. By removing contaminants, water, and entrained air before fuel ever reaches the pump and injectors, this system helps extend the life of both your injection system and your injectors.
FASS engineered this fuel system to be the top-performing, longest-lasting, and most reliable aftermarket filtration system in the diesel industry. It is backed by a limited lifetime warranty, giving you long-term confidence in the fueling upgrade you install.
The Plus Difference
What sets the Plus apart from the standard Titanium Signature Series is its attention to installation detail and finish. It comes equipped with ORB (O-Ring Boss) fittings, 6061 aluminum black anodized fittings, and black fuel line for an exceptionally clean, cohesive install. The system is constructed from durable 6061 T-6 billet aluminum with a black finish, so it looks as purposeful as it performs.
