Description
Overview
The FASS Titanium Signature Series Plus Fuel System is the next evolution of the popular Titanium Signature Series, purpose-built for the 2020-2023 GM Duramax 6.6L. Engineered by FASS Fuel Systems to be a top-performing, long-lasting, and reliable aftermarket lift pump and filtration system, it delivers a steady, high-volume supply of clean fuel to your Chevrolet or GMC Duramax injection system. Rated at 100 gallons per hour and operating at 70-75 psi, it has the capacity to support builds making anywhere from 900 up to 1200 horsepower.
Advanced Filtration & Air Removal
Duramax diesel engines are well known for fuel-related injector failure, and FASS filtration is designed to eliminate exactly those issues. The Signature Series Plus combines an improved 2-micron filtration rating with a built-in water separation filter and the FASS patented air/vapor removal process. Together these features protect your injection system and injectors from contaminants, water, and entrained air, effectively extending the life of both your injectors and the entire injection system on your 6.6L Duramax.
The ‘Plus’ Upgrade & Clean Installation
What sets the Plus apart is a refined, ultra-clean installation. It comes equipped with ORB (O-Ring Boss) fittings, 6061 aluminum black anodized fittings, and black fuel line for a stealthy, factory-quality look under the hood and along the frame rail. The system is constructed from durable 6061 T-6 billet aluminum finished in black, so it looks as purposeful as it performs.

Why It Matters for Your Duramax
A high-horsepower Duramax demands consistent fuel volume and clean, air-free diesel to keep its injectors and injection system healthy. By pulling fuel from the tank, filtering it to 2 microns, separating out water, and removing damaging air and vapor before it reaches the engine, the Titanium Signature Series Plus addresses the root causes of many fuel-related injector problems. The result is protection for expensive injection components and the headroom to feed serious power.
