Description
Overview
The FASS Titanium Signature Series Diesel Fuel System (Part No. TSC10250G) is a dedicated, air/vapor-separating lift pump and filtration system engineered specifically for the 2001-2016 GM Duramax 6.6L. Unlike many other diesels, the Duramax doesn’t come with a factory lift pump, which forces your CP3/CP4 injection system to pull fuel under a vacuum. That added strain, combined with the risk of air and vapor entering your fuel, can shorten the life of your injection components. The Titanium Signature Series solves that problem by delivering clean, consistent, de-aerated fuel directly to your injection system.
Rated at 250 gallons per hour (250GPH) and maintaining a steady 8-10 PSI, this Super Extreme configuration is built to support GM Duramax engines producing between 900 and 1200 horsepower. It’s sold as a complete kit, ready to become the reliable fuel foundation your build demands.
Key Benefits
FASS engineered the Titanium Signature Series to be a top-performing, long-lasting, quiet and reliable aftermarket filtration system. Beyond simply supplying fuel volume, its advanced filtration actively removes contaminants and separates damaging air and vapor from your diesel. The result is cleaner fuel, reduced stress on your CP3/CP4 pump, and extended injection system life.
Constructed from durable 6061 T-6 billet aluminum with a black finish, the system is designed to hold up to the demands of high-horsepower diesel performance. It is also backed by an available limited lifetime warranty from FASS, reflecting the durability engineered into every unit.

Why It Matters for Your Duramax
Because the Duramax relies on its injection system to draw fuel under vacuum from the factory, adding a dedicated FASS system fundamentally changes how your truck manages fuel. Removing entrained air and vapor allows the injection system to work with a consistent, pressurized supply rather than fighting for fuel. This translates to a healthier injection system, better protection against contaminants, and greater peace of mind whether you’re towing, daily driving, or pushing big power.
Fitment
This Titanium Signature Series fuel system is designed for the 2001-2016 GM Duramax 6.6L Truck and SUV applications. Verify your model year against the 2001-2016 range to confirm compatibility before installation, and choose this Super Extreme 250GPH configuration when your goal is maximum fuel support for high-horsepower performance.
