The FASS TS D08 165G Titanium Signature Series 165GPH Fuel System with Whisper Technology is engineered to be the top performing, longest lasting and most reliable aftermarket filtration system on the market for your 1998.5-2004.5 Dodge Ram 5.9L Diesel. Rated at 165 gallons per hour and backed by a limited lifetime warranty, the Titanium Signature Series offers advanced filtration that will help protect your Diesel 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. For moderate to extreme engines 600HP-900HP 

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 Specd 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 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.

Bolt On Bracket Mounts
Old mounting styles required drilling or welding when mounting your pump. This has been simplified with the FASS bolt on brackets that utilize your factory bed bolt that secures your truck bed to the frame. Mounting the Titanium Signature Series Pump takes only minutes and all brackets are made from machined steel for durability, support and strength.
