A couple of years ago, we had the opportunity to sit down with Patrick at The Diesel Podcast to talk about one of the most important—and often overlooked—upgrades for any diesel truck: fuel system filtration.
In this interview, Spencer Ekstam (Co-Owner & Operations Manager) and Josh Thornton (Lead Engineer) from FASS Diesel Fuel Systems break down why we confidently say: “Every truck needs this upgrade.”
Why Fuel Filtration Matters More Than You Think
During the conversation, Spencer and Josh dive into the real reason behind that statement.
Modern diesel engines—whether stock or heavily modified—are extremely sensitive to fuel quality.
Even small amounts of
air, water, or debris can lead to:
- Premature injector wear
- Reduced fuel lubricity
- Inconsistent fuel pressure
- Loss of performance over time
FASS Diesel Fuel Systems are designed to solve those issues by delivering
clean, air-free fuel to the engine—helping improve reliability, drivability, and long-term component life.
More Than a Performance Upgrade
One of the biggest takeaways from the podcast is that FASS systems aren’t just for high-horsepower builds.
They’re built for:
- Daily drivers
- Tow rigs
- Work trucks
- Fleet vehicles
- Performance applications
At the end of the day,
anything that runs on diesel benefits from better fuel filtration.

Final Thoughts
The idea is simple: clean fuel equals longer-lasting components and better performance.
That’s why we stand behind it—every truck really does need this upgrade.
