Description
Overview
The No-Drop Series Plus Fuel System from FASS Fuel Systems is purpose-built for the 2020-2023 Chevrolet Silverado and GMC Sierra Duramax 6.6L trucks running stock to 500hp. This kit represents the next evolution of the popular Titanium Signature Series Fuel System, now upgraded to Plus specification with ORB (O-Ring Boss) fittings, 6061 T-6 billet aluminum black anodized fittings, and black fuel line for a clean, professional-grade install. If you’re looking to eliminate fuel starvation, protect your injection system, and simplify the install process, this No-Drop Plus Kit delivers a complete, purpose-matched solution.
What sets the No-Drop Plus Kit apart is exactly what its name implies-no dropping the fuel tank. FASS engineered these kits around a dedicated Fuel Sump, which eliminates the need to remove your tank for installation. That means less labor, less downtime, and less hassle getting your Duramax back on the road with a properly supported fuel system. Buying the No-Drop Plus Kit also delivers real savings compared to purchasing a Titanium Signature Series Plus Fuel System and Sump Kit separately-you get everything necessary for a straightforward FASS installation, and nothing you don’t need.
Key Benefits
At the core of the No-Drop Plus Kit is fuel filtration and delivery performance that goes well beyond what the factory system provides. The system increases fuel lubricity by at least 10 percent, which can triple the life of your injection components. It removes over 99 percent of the water content from your fuel and eliminates entrained air and vapor that can rob your engine of consistent fuel pressure. Filtration is rated down to 2 microns absolute, catching the debris that OEM systems let through, while fuel flow far exceeds stock output. The system is designed to operate at 70-75 psi, and electric fuel heater kits are available separately for cold-weather environments.
Construction & Fitment
Built from 6061 T-6 billet aluminum and finished in black, this No-Drop Plus Kit is engineered specifically for 2020-2023 Duramax 6.6L Silverado, Sierra, and SUV applications running stock output up to 500hp. It is sold as each and manufactured by FASS Fuel Systems under the No Drop Series line.
Why It Matters
For Duramax owners who want a dependable, high-performance fuel supply without the extra labor of a full tank drop, the No-Drop Series Plus Fuel System offers a direct path to better fuel quality, more consistent pressure, and stronger long-term protection for injectors and injection pumps alike.
