Titanium Signature Series
The Titanium Signature Series is our most versatile FASS System. It is the #1 pump used by Pickup and Class 8 drivers. The Steel Bracket design allows you to tuck the pump closer to the frame for better clearance and less visibility. This pump has the capability to flow up to 290 gallons per hour, boasts large filters for long stays on the road and has all half inch ports with half inch fuel line. Accessory ports also enable additional FASS pumps to work in conjunction with the Titanium Signature Series to achieve flow rates above 290 gallons per hour for custom applications. The Titanium Signature Series is the premier pump in the FASS line.
