FASS has engineered the TS 165G Titanium Signature Series 165 GPH Fuel System with Whisper Technology to be the top-performing, longest lasting, and most reliable aftermarket filtration system on the market. Rated at 165 gallons per hour and backed by a limited 4 year warranty, the Titanium Signature Series offers advanced filtration that will help protect your fuel injection system, effectively extending the life of your Injection Pump and Injectors. These benefits include: improved filtration rating of 3 Microns, a built-in water separation filter and FASS Fuel Systems patented air/vapor removal process.

Titanium Signature Series 

With over 2.5 years in the making, FASS has done extensive testing, research, and manufacturing on their Signature Series Fuel Systems. Featuring the FASS Whisper Technology specially designed to decrease pump noise, improve pump life, improve flow rate, and increase overall pump performance, the Signature Series provides you with the most reliable aftermarket fuel system in the industry.

FASS Silencing Technology (FST)

Developed by the engineering team at FASS Fuel Systems to help reduce the noise created by aftermarket fuel and air separation systems. By using radius cuts, tighter tolerances on all gears and a high quality military Spec Coating over the aluminum base, FASS Fuel Systems is able to develop the quietest fuel air separation system on the market.

Performance Radius Cuts (PRC)

An advanced machining technique is used to improve the flow of fuel through the pump by creating smooth flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and also to prevent stagnant fuel pockets from forming within the corner of a 90-degree bend. FASS Titanium Signature Series Fuel Pumps are the only Fuel Air Separation System that incorporates these exclusive Performance Radius Cuts, lesser competitors commonly use T-Bone and square 90 degree fittings that can limit fuel flow, cause restrictions and reintroduce air back into your fuel.

Mass Flow Return (MFR)

Technology is used to continually “polish” your fuel by keeping a positive pressure on the fuel being delivered to the engine and returning the fuel, that’s not yet needed, back to the tank after it has been passed through the filtration process, removing dirt, air, vapor, and water. This means your fuel is constantly being moved and cleaned. This guarantees that your truck always has the freshest and cleanest fuel possible.
