A Titanium Signature Series System also offers advanced filtration benefits that will help protect your Duramax’s injection Systems, effectively tripling the life of your injection system and injectors. Benefits include an improved filtration rating of 2 Microns, a built in water separation filter and FASS Fuel Systems patented air\/vapor removal process. Duramax diesel engines are known for having injector failure issues; this can be caused by several different factors and FASS Filtration Systems is designed to eliminate those that are fuel related. The Titanium Signature Series diesel fuel systems are the superior fuel system and filtration system, in the diesel industry. This is because at FASS Fuel Systems we focus on perfecting our systems and how they are engineered, taking the extra steps that our competitors ignore while they rush to get product out the door. By doing our homework we have less than a 1% failure rating with our motor and a design that implements unique design features you can only get with FASS Fuel Systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFASS Whisper Technology (FWT)\u003c\/strong\u003e was engineered to meet the stringent demands of  today’s quiet diesel engines.

FASS Whisper Technology effectively and drastically reduces the sound levels of the Titanium Signature Series FASS Diesel Fuel System to a “whisper” while at the same time increasing fuel flow rates.

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.
