Description
Overview
The FASS No Drop Series Diesel Fuel System is engineered for the 2020-2023 GM Duramax 6.6L in the demanding 900-1200hp range. This complete package pairs the Titanium Signature Series Fuel System (TSC15290F240G) with the FASS SK5501 Diesel Fuel Sump Kit, giving you everything needed for a clean, straightforward installation and nothing you don’t. Machined from durable 6061 T-6 Billet Aluminum and finished in black, it’s built to deliver reliable, high-volume fuel delivery to your Duramax.
Why the No Drop Series
Installing a Titanium Signature Series Fuel System has never been easier or more affordable. The No Drop concept centers on the included Fuel Sump, which eliminates the need to remove your fuel tank during installation. That means less labor, less hassle, and a genuinely simplified setup. On top of the convenience, bundling the fuel system and sump together delivers significant savings over purchasing the Titanium Signature Series Fuel System and Sump Kit separately.
Performance & Fuel Quality
The Titanium Signature Series pump in this kit flows 240GPH at 70-75 PSI, providing far more fuel flow than the OEM system to support big-power builds. Beyond raw volume, FASS is about fuel quality and protecting your investment. The system removes over 99 percent of the water from your fuel, eliminates entrained air and vapor, and filters debris down to 2 microns absolute. It also increases fuel lubricity by at least 10 percent, which can help extend the life of your injection components up to three times.
