Description
Overview
The FASS No Drop Series Diesel Fuel System is a complete, ready-to-install fuel delivery upgrade built for the GM/Chevy Duramax 6.6L. Engineered by FASS Fuel Systems, this No Drop Kit pairs the Titanium Signature Series Fuel System with a FASS Diesel Fuel Sump Kit so you get everything needed for a clean, straightforward installation—and nothing you don’t. It’s designed to simplify the job, deliver serious savings over buying the components separately, and protect the heart of your diesel: the injection system.
What makes the No Drop concept so appealing is the included Fuel Sump. By drawing fuel through a sump, this kit eliminates the need to remove your fuel tank during installation, turning what is often a labor-intensive project into a much more manageable upgrade. That means less time in the shop and a faster path to cleaner, better-flowing fuel.
Key Benefits
At its core, this system is about giving your engine consistently clean, air-free, water-free diesel at flow rates that far exceed what the factory setup can provide. It increases fuel lubricity by at least 10 percent and can help triple the life of your injection components—an especially meaningful advantage on hard-working Duramax trucks and SUVs. Combined with best-in-class filtration and air/vapor separation, it’s a comprehensive fuel-quality solution.
- Increases fuel lubricity by at least 10 percent
- Can 3x the life of injection components
- Removes over 99 percent of the water from fuel
- Eliminates entrained air and vapor
- Filters out debris down to 2 microns absolute
- Provides far more fuel flow than OEM

What’s Included
Each No Drop Kit ships as a matched package so you’re not sourcing parts piecemeal. Inside you’ll find one (1) Titanium Signature Series Fuel System rated at 240 GPH and 70–75 PSI (TSC10165G), plus one (1) FASS Fuel Sump Kit (SK5501). The sump is what allows you to skip dropping the fuel tank, making this an ideal bundle for anyone who wants a professional-grade FASS setup without the added complexity.
Construction & Fitment
The system is built from rugged 6061 T-6 billet aluminum with a black finish for durability under the truck. This No Drop Series Diesel Fuel System is intended for the 2001-2010 GM/Chevy Duramax 6.6L platform in the 600–1,000hp range, with fitment for 2001-2004 Duramax Truck/SUV applications. It is sold as each, delivered as a complete kit ready for your build.
For Duramax owners chasing longer injector life, cleaner fuel, and stronger, more consistent fuel delivery, the FASS No Drop Series is a smart, cost-effective way to get the proven performance of a Titanium Signature Series system with sump-simplified installation.
