FASS No-Drop Titanium Signature Series PLUS Fuel System for GMC/Chevrolet 2001–2010 Duramax 6.6L
If you drive a 2001–2010 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 operations 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 built to outlast it.
The Titanium Signature Series PLUS Fuel System is designed for customers who want all the performance and protection of a FASS Titanium Signature Series fuel system with upgraded black anodized ORB (O‑Ring Boss) fittings at the filter base and all black anodized AN‑style fittings throughout.
