Description
Overview
The FASS Titanium Signature Series Diesel Fuel System (TSD07250G) is a 250GPH dedicated fuel system engineered for Dodge Ram Cummins 5.9L and 6.7L trucks and SUVs from 2005-2018, with coverage extending to 2021. Built by FASS Diesel Fuel Systems as the flagship of the Titanium Signature Series lineup, this system is designed to be a top-performing, long-lasting, and reliable aftermarket fuel filtration and delivery solution for high-demand diesel applications. Sold as a complete kit, the housing is machined from 6061 T-6 billet aluminum and finished in a durable black, giving it the strength and corrosion resistance needed for long-term underhood or in-cab service.
This is the Super Extreme configuration, rated to support 900-1200 HP, making it purpose-built for aggressive fueling setups, large injector upgrades, and multiple performance modifications often used in towing, sled pulling, or competition environments. Operating pressure is maintained at a steady 16-18 PSI, delivering the consistent fuel pressure that high-output Cummins engines demand under load.
Key Benefits
Beyond raw flow capacity, the Titanium Signature Series is built around advanced filtration to protect your entire fuel and injection system. A 2-micron filtration rating captures fine contaminants before they reach your Bosch injection pump and injectors, while a built-in water separation filter pulls damaging moisture out of the fuel before it can cause corrosion or injector failure. FASS’s patented air/vapor removal process further protects fuel quality by eliminating vapor and air pockets that can cause fuel starvation, hard starts, or inconsistent power delivery — a critical feature for trucks pushing serious horsepower.
Because this system is engineered for both extreme performance builds and everyday reliability, it’s suited to daily-driven Cummins trucks that have been upgraded with larger injectors or tuning, as well as dedicated competition and towing rigs that need dependable, high-volume fuel supply at all times.
Fitment
This FASS Titanium Signature Series 250GPH kit is designed to fit 2005-2018 Dodge Ram Cummins 5.9L and 6.7L trucks and SUVs, with coverage for 2021 model applications as noted by the manufacturer. Confirm your specific model year and engine configuration against your vehicle’s fuel system requirements before installation.
