2015-2016 Duramax LML FASS No‑Drop Series 165G Fuel System (NDTSC12165G)
If you drive a 2015-2016 GMC/Chevrolet with the Duramax 6.6L LML diesel engine, upgrading your fuel filtration and delivery WILL TRIPLE the life of the injection system, increase MPG and power, and provide exceptional extreme cold weather operation.
That’s exactly why we engineered the Titanium Signature Series Fuel System, to outlast and outperform anything else on the market. This system is designed to provide the purest possible fuel to your Duramax and built to outlast it.
Without proper fuel filtration, diesel injection systems are prone to excessive wear that can cost thousands. The Titanium Signature Series removes over 99% of the water from your fuel along with air, vapor, and debris down to 2 microns absolute, delivering clean, conditioned fuel to your engine at a consistent pressure. It WILL TRIPLE the life of your fuel injection components, and more for the CP4-equipped LML Duramax.
The No-Drop Titanium Signature Series Fuel System is designed for customers who want all the performance and protection of a FASS fuel system without dropping the fuel tank. Instead of a traditional sump, this system uses a bolt-in suction tube and bulkhead assembly (BHF-1005) installed opposite the factory fuel module opening, so there is no tank drop and no filler neck cutting while the FASS still gets proper fuel supply, filtration, and return.
This kit pairs the Titanium Signature Series Fuel System with the FASS bulkhead and suction tube kit (BHF-1005) and offers significant savings over buying the two separately. It includes everything you need for a simple, straightforward FASS installation, and nothing you don't. The bulkhead bolts in opposite the factory fuel module opening and gives both FASS fuel lines a direct connection to the tank, eliminating one of the most labor-intensive steps of a traditional installation.
