Engineered for 2005–2018 and 2021–2024 Dodge Ram 2500 and 3500 diesel trucks powered by the 5.9L Common Rail or 6.7L Cummins engine, the FASS Titanium Signature Series 250 GPH Fuel Air Separation System (TSD07250G) is purpose-built for extreme-horsepower competition, heavy sled pulling, and aggressive dual-CP3 builds. Severe fueling demands exceeding 900 horsepower can instantly empty low-pressure fuel tracts, creating severe vacuum drops and cavitation that cause catastrophic injection pump failure. The TSD07250G guarantees relentless, high-volume positive fuel supply under prolonged wide-open throttle.

This competition-grade kit includes two FASS BHF-1005 6061-T6 billet aluminum bulkhead fittings and oversized PTFE Teflon suction tubes, providing an unrestricted high-flow fuel draw through the factory fuel tank module without cutting the filler neck. As diesel fuel circulates through the Titanium housing, FASS Whisper Technology (FWT) and Performance Radius Cuts (PRC) eliminate turbulence and acoustic chatter while preserving maximum volume delivery. Operating in tandem with the Mass Flow Return (MFR) system, the pump continuously polishes fuel by stripping entrained air bubbles, vapor pockets, and over 99% of moisture, filtering particulate down to 2 microns absolute to keep race-modified common rail injection systems fully protected.

Key Features & Benefits

• Supports 900 to 1,200+ Horsepower: Massive 250 gallons per hour delivery rate at a constant 16–18 PSI satisfies the severe fueling demands of dual-CP3 pumps, large-displacement injectors, and multi-stage turbochargers.
• 2-Micron Absolute Particulate Filtration: Traps microscopic soot and debris down to 2 microns absolute, defending ultra-tight-tolerance competition injector plungers and nozzles against abrasive wear.
• Over 99% Water Separation: High-capacity water separation canister prevents both free and emulsified moisture from reaching expensive high-pressure common rail components.
• Patented Air & Vapor Separation: FASS Mass Flow Return continuously purges entrained air and vapor back to the tank, boosting fuel lubricity by at least 10% to prevent scoring and idle instability.
• FASS Whisper Technology (FWT): Precision gear profiles, tight internal tolerances, and military-grade coatings reduce motor resonance to a quiet hum despite extreme output volume.
• Performance Radius Cuts (PRC): Smooth, radiused fluid channels eliminate sharp 90-degree internal turns, eliminating eddy currents and stopping cavitation before it starts.
• Bolt-On Steel Mounting Brackets: Heavy-duty machined steel mounting brackets attach securely to factory bed-to-frame bolt locations without requiring frame drilling or welding.

Vehicle Fitment & Installation Notes

• 2005–2007 Dodge Ram 2500 / 3500 – 5.9L 24V Common Rail Cummins
• 2007.5–2009 Dodge Ram 2500 / 3500 – 6.7L 24V Cummins Turbo Diesel
• 2010–2018 Ram 2500 / 3500 – 6.7L 24V Cummins Turbo Diesel
• 2021–2024 Ram 2500 / 3500 – 6.7L 24V Cummins Turbo Diesel
• Fitment Notice: Standalone system that utilizes the included bulkhead and suction tube kit (requires dropping the fuel tank or unbolting the truck bed to access the module). Does not fit 2019–2020 Ram trucks without custom plumbing due to factory fuel line variations (use TSD12250G for 19–20). Cab & Chassis configurations may require custom mounting considerations.
• Installation Tip: Due to the extreme suction demand of a 250 GPH pump, ensure the PTFE suction tube is trimmed cleanly to leave 1/4" clearance from the bottom of the module basket, and check that all 1/2" supply hose runs are free of sharp kinks along the chassis frame.
