Description
Overview
The FASS Titanium Signature Series Diesel Fuel System delivers a purpose-built lift pump and filtration upgrade for the 2015-2016 GM Duramax LML 6.6L. Unlike many diesels, the Duramax doesn’t leave the factory with a dedicated fuel supply system, which forces the CP4 injection system to draw fuel under a vacuum. That added stress and the risk of introducing air into the fuel can shorten the life of critical injection components. The Titanium Signature Series (Part No. TSC12100G) was engineered by FASS Fuel Systems to solve exactly that problem, supplying clean, consistent, air-free fuel to protect and support your engine.
Key Benefits
Rated at 100 gallons per hour and regulated to a steady 8-10 PSI, this system is built to keep up with a Stock to Moderate build in the 0-600 HP range, leaving plenty of headroom to support multiple fueling system upgrades down the road. Advanced filtration removes contaminants and separates air and vapor from the fuel, helping extend the service life of your injection system and injectors.
Constructed from durable 6061 T-6 billet aluminum in a clean black finish, the Titanium Signature Series is designed to be a top-performing, long-lasting, and reliable aftermarket filtration system. It’s backed by a FASS limited lifetime warranty, reflecting the confidence FASS places in its engineering and build quality.

Why It Matters for Your Duramax
Because the LML Duramax relies on the CP4 to pull fuel on its own, adding a dedicated FASS system relieves that burden and reduces the chance of air-related wear. The result is a more stable fuel supply, cleaner fuel reaching the injectors, and added protection for some of the most expensive components on the engine. Whether you’re running a stock truck that you want to keep reliable for the long haul or building toward moderate performance goals, the extra flow capacity ensures your fuel delivery keeps pace with your plans.
