FASS No-Drop Series PLUS 140G Fuel System for GMC/Chevrolet 2017-2019 Duramax 6.6L

FASS No-Drop Series PLUS 140G Fuel System for GMC/Chevrolet 2017-2019 Duramax 6.6L

If you drive a 2017–2019 GMC/Chevrolet with the Duramax diesel engine, upgrading your fuel filtration and delivery will triple the life of the injection system, increase MPG & power, provide exceptional extreme cold weather operation, and more.

That’s exactly why we engineered the Titanium Signature Series PLUS Fuel System—to outlast and outperform anything else on the market. This fuel system is designed to provide the purest possible fuel to your Duramax and is built to outlast it.

The No-Drop Titanium Signature Series PLUS Fuel System is designed for customers who want all the performance and protection of a FASS fuel system without dropping the fuel tank. This system utilizes our 6061‑T6 billet aluminum Single Bolt Fuel Sump with a suction port and a return port, using one single hole in the bottom of the fuel tank. The FASS will draw and return its fuel to the sump, giving you an ultra‑clean and simple installation.
