Fuel quality matters—a lot. Many diesel owners don’t even realize how important clean fuel really is—it majorly impacts things like:
- Injection System Life (thousands of $$$ to replace)
- Fuel Economy
- Horsepower
- Throttle Response
- Soot/Smoke Output
- And more!
And believe it or not, the #1 contaminant in your fuel is (drumroll) air. Yep, you read that right—air and vapor, which makes up at least 10% of stationary diesel fuel, is the #1 cause of hydraulic system failures.
And if you don’t know—your Duramax’s injection system is a hydraulic system! Simply put, the air/vapor, water, and debris found in diesel fuel is slowly (and sometimes quickly) creating expensive problems.
Upgrading your 2017+ 6.6 L5P Duramax fuel filtration:
Installing best fuel filtration (3rd party proven) on your 2017+ Chevrolet/GMC truck is much, much easier than you might think.
Our Drop-In Series Fuel Systems are a bolt-in, plug-and-play filtration upgrade that eliminates:
- Entrained air and vapor
- Over 99% of water (In the event of extreme fuel contamination, our Extreme Water Separator also functions as a water dam, preventing thousands of dollars in damage.)
- Debris down to 2 Microns absolute
The best part, Drop-In Series Fuel Systems can be installed right in your driveway using basic hand tools. These kits utilize your factory in-tank lift pump for fuel flow while providing full FASS filtration—so there’s no need to lower your fuel tank to install!
Upgrade your 2017+ 6.6 L5P Duramax fuel filtration AND flow:
For L5P Duramax owners looking to upgrade their fuel filtration and fuel flow, our Titanium Signature Series and Titanium Signature Series PLUS Systems are just what the doctor ordered.
While our Drop-In Series Fuel Systems utilize the factory in-tank fuel pump for flow, our Titanium Signature Series and Titanium Signature Series PLUS Systems replace the factory fuel pump altogether.
These systems are perfect for:
- Tuned/modified 2017+ Silverados/Sierras that require more fuel flow than the factory pump can provide.
- 2017+ Silverado/Sierras with higher miles that may experience factory fuel pump failure in the near future.
Please Note: While our Drop-In Series Systems for the 2017+ Duramax are 100% bolt-in with zero modifications needed, Titanium Signature Series and Titanium Signature Series PLUS Systems are designed for 2017+ Duramax trucks with aftermarket tuning.
Installing a Titanium Signature Series or Titanium Signature Series PLUS System on a 2017+ Silverado/Sierra that has not been tuned will cause a check engine light to appear. If you have not tuned or do not wish to install an aftermarket tune on your 2017+ Duramax, please utilize our Drop-In Series Fuel System.
