The Titanium Signature Series Plus is the next evolution of our popular Titanium Signature Series Fuel System. The Titanium Signature Series Plus is equipped with ORB (O-Ring Boss) Fittings, 6061 aluminum black anodized fittings, and black fuel line for an ultra-clean installation!

This Fuel System was engineered by FASS to be the top-performing, longest-lasting, and most reliable aftermarket filtration system in the diesel industry.  

This Fuel System also offers advanced filtration benefits that will help protect your Cummins injection Systems, effectively extending the life of both your Injection System and Injectors. These Benefits include an improved filtration rating of 2 Microns, a built-in water separation filter, and FASS Diesel Fuel Systems patented air/vapor removal process.


Titanium Signature Series Plus Fuel Systems lead the diesel industry in both quality and effectiveness.  This is because here at FASS, we focus on perfecting our Fuel Systems and how they are engineered—taking the extra steps that our competitors simply do not. By doing this, we have less than a 2% failure rating with our motor, and a design that implements unique design features you can only get with FASS Diesel Fuel Systems.

• FASS Whisper Technology (FWT) effectively and drastically reduces the sound levels of the Signature Series Plus FASS Diesel Fuel System to a “whisper” while at the same time increasing fuel flow rates. Our competition reduces noise levels by reducing flow rates.


• Performance Radius Cuts (PRC) are an advanced machining technique used to improve the flow of fuel through the FASS System by creating smooth-flowing cuts within the aluminum housing. This prevents the reintroduction of air and vapor back into the fuel and prevents eddy currents from forming within the corner of a 90-degree sharp angle. FASS Titanium Signature Fuel Systems 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 to prevent cavitation along with galling and scoring. Then 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 being constantly “Polished” (cleaned), guaranteeing that your diesel truck always has the cleanest fuel possible. The MFR in combination with the optional FASS Fuel Heater options will help insure “EXTREME” cold weather operations!


• Bolt On Bracket Mounts old mounting styles required drilling or welding when mounting your new System. This has now been simplified with our new bolt on brackets that utilize your factory bed bolt, the bolt that secures your truck bed to your frame. Mounting your Titanium Signature Series Plus System takes only minutes, and all brackets are made from machined steel for superior support and strength.
