Description
Overview
The FASS Titanium Signature Series Diesel Fuel System delivers a dedicated fuel supply and advanced filtration package engineered specifically for the 2011-2014 GM Duramax LML 6.6L. Unlike some diesels, your Duramax doesn’t come with a factory lift pump, which forces the CP3 injection system to pull fuel under a vacuum. That extra stress on the CP3 and the risk of drawing air into your fuel can shorten the life of expensive components. This complete FASS system solves that problem at the source.
Rated at 100 gallons per hour and holding a steady 8-10 PSI, the Titanium Signature Series (part number TSC11100G) is built to support stock to moderate builds in the 0-600 HP range. That flow capacity leaves headroom for multiple fueling system upgrades, so the pump can grow with your truck rather than becoming a bottleneck.
Advanced Filtration & Protection
FASS engineered the Titanium Signature Series to be a top-performing, long-lasting and reliable aftermarket filtration system. By separating air and vapor from the fuel and providing improved filtration, this system helps protect your Duramax’s injection system and injectors, effectively extending their service life. Cleaner, air-free fuel means your CP3 and injectors work under far less strain than they would relying on the factory vacuum-fed setup.
Built to Last
The pump body is machined from 6061 T-6 billet aluminum and finished in black, giving it the durability and corrosion resistance needed for a demanding under-truck environment. Backed by a limited lifetime warranty from FASS Fuel Systems, this is a system designed to run hard for the long haul.

Fitment
This system is designed for the 2011-2014 GM Duramax LML 6.6L truck and SUV applications. Because the Duramax lacks a factory lift pump, adding a dedicated FASS system is one of the most beneficial upgrades you can make — relieving the CP3 of vacuum duty, removing entrained air, and delivering clean, consistent fuel to the injection system.
Whether you’re protecting a daily-driven stock truck or feeding a modified build with additional fueling upgrades, the Titanium Signature Series 100GPH provides the flow, filtration, and reliability your Duramax deserves. Add a dedicated fuel supply system that safeguards your injectors, stabilizes fuel delivery, and supports future performance goals in one purpose-built kit.
