Most diesel owners know that water is one of the
worst contaminants that can enter a fuel system. But have you ever wondered what actually happens when water, a LOT of water, gets into the tank—and whether your fuel filtration system can really remove it?
In our latest video, Brad Ekstam, Founder and President of FASS Diesel Fuel Systems, and Josh Thornton, Lead Engineer, decided to show you
exactly how a FASS Fuel System tackles water contamination.
The test vehicle? Brad's personal 2024 Ford F-450. The test? Pouring a cup of good 'ol water directly into the fuel tank.
Putting FASS Filtration to the Test
Rather than relying on countless hours of testing and 3rd party labs (which we've also done), Brad and Josh wanted to show a real-world example of how FASS filtration handles water contamination.
As the truck runs, the FASS Fuel System begins doing exactly what it was engineered to do:
- Remove over 99% of the water from the fuel supply
- Trap the water within the FASS Extreme Water Separator—ensuring it never reaches the injection system
- Separate entrained air and vapor
- Deliver clean fuel to the injection system
What makes this demonstration especially interesting is that the entire process is monitored in real time using
FASS Connect.
Watching Fuel Filter Life in Real Time
Throughout the test, Brad's
FASS Connect Data Monitoring System tracks the condition of the filters as they capture and remove the water contamination.
Using the FASS Connect app and monitoring system, viewers can actually watch the system respond to the contaminated fuel and see how the filters handle the challenge.
It's a great example of how FASS Connect gives owners unprecedented visibility into the health of their fuel system.
The Results Speak for Themselves
By the end of the test, a single set of FASS filters successfully removes the water contamination from the fuel system, helping demonstrate the importance of proper filtration in protecting modern diesel engines.
While nobody is recommending intentionally adding water to your fuel tank, this test highlights an important reality:
- Bad fuel happens.
- Condensation happens.
- Water contamination happens.
The question isn't whether water will eventually find its way into a fuel system—it's whether your filtration system is prepared to handle it.

Final Thoughts
At FASS, we've always believed that protecting diesel fuel systems starts with delivering the cleanest fuel possible.
This demonstration showcases exactly why proper filtration matters and how FASS Fuel Systems and FASS Connect work together to help protect your truck from harmful contaminants.
