Advanced Filtration and Protection
Duramax diesel engines are well known for fuel-related injector failure issues, and FASS filtration systems are designed to eliminate those that originate in the fuel supply. The Titanium Signature Series Plus provides advanced filtration that helps protect your injection system and dramatically extends the life of your injectors. Those benefits include an improved 2-micron filtration rating, a built-in water separation filter, and FASS Diesel Fuel Systems’ patented air/vapor removal process, which strips damaging air and vapor out of the fuel before it ever reaches the injectors.
