Description
Overview
The FASS TSD12250G Titanium Signature Series Diesel Fuel System is engineered by FASS Fuel Systems to be a top-performing, long-lasting, and reliable aftermarket filtration system for your 2019-2020 RAM 6.7L Cummins. Rated at 250 gallons per hour (GPH) and operating in the 8-10 PSI range, this dedicated fuel system is built to feed a Super Extreme 900-1200 HP application with enough fuel to support multiple fueling upgrades. Whether you drive daily or push serious power, this system delivers clean, consistent fuel to keep your Cummins running strong.
Advanced Filtration & Injection Protection
Beyond raw flow, the Titanium Signature Series is about protection. Its advanced filtration helps safeguard your injection system and extend the life of both your Bosch injection system and Bosch diesel injectors. The system combines an improved 2-micron filtration rating, a built-in water separation filter, and FASS Fuel Systems’ patented air/vapor removal process. Together, these features strip out contaminants, water, and entrained air before they ever reach your injectors, protecting the components that keep your Cummins reliable.
Built Tough, Built to Last
Machined from 6061 T-6 billet aluminum and finished in black, the Titanium Signature Series is constructed for durability and long service life. It arrives as a complete kit and is backed by a limited lifetime warranty, reflecting the confidence FASS places in its filtration and fuel delivery engineering. This kit also includes two FASS BHF-1005 Bulkhead and Suction Tube Kits to complete the installation.
Why It Matters
An aftermarket fuel system is valuable for both daily drivers and high-performance builds. If you’re looking to improve fuel economy or increase horsepower and torque, delivering a steady, clean, air-free supply of diesel is fundamental. The TSD12250G is designed to meet those demands, supplying the fuel volume needed for aggressive tuning and added injectors while simultaneously protecting the expensive Bosch components downstream.
