Cleaner Installation, Advanced Engineering

The result is a fuel system that not only performs but looks the part on your Duramax truck or SUV.
Protect Your Injection System
Duramax diesel engines are known for fuel-related injector failure issues, and FASS filtration systems are designed to eliminate those problems at the source. The Titanium Signature Series Plus offers advanced filtration benefits that protect your injection system and extend the life of both your injectors and pump. These benefits include an improved 2-micron filtration rating, a built-in water separation filter, and the FASS patented air/vapor removal process that strips damaging air and vapor out of the fuel before it reaches your engine.
