We get asked all the time:
“My truck is stock, is a FASS Fuel System really worth installing?”
After all, we’ve built a strong reputation in the diesel performance world—with our fuel systems supporting thousands of 1,000+ horsepower trucks. But the truth of our product line is so, so much bigger than power.
TLDR: FASS Diesel Fuel Systems were originally designed for bone-stock class 8 trucks—to optimize MPG, increase injection system life, restore horsepower and more. And, the vast majority of our fuel systems are purchased for stock or nearly-stock trucks. If you want to get the most from your diesel truck, maximizing fuel quality with a FASS Fuel System is a no-brainer.
Why install a FASS on a stock truck?
As mentioned above, the heart of FASS technology is our industry-leading fuel filtration. Through decades of development and consistent 3rd party testing, we have engineered fuel systems that deliver the purest fuel possible to your engine.
To achieve this, our systems:
- Eliminate over 99% of the water from your fuel
- Remove entrained air and vapor (diesel fuel is at least 10% air when stationary)
- Filters out debris down to 2 Microns Absolute
- Continually polishes the fuel as your truck runs
This extreme level of fuel filtration can deliver eye-opening (and money saving) results. Including but not limited to:
- 3x injection system life
- Improved MPG* (results will vary)
- Restored horsepower
- Reduced soot/smoke output
- Smoother idle
- Sharper throttle response
- And more!
When you think about a FASS Fuel System in terms of fuel filtration, there isn’t a diesel-powered truck on earth that wouldn’t benefit from one!
*MPG improvements are affected by record-keeping methods, driving habits, fuel quality, and location. Due to these factors, among others, FASS cannot guarantee a measurable MPG increase.
So why do all these high-horsepower trucks have them?
We are so, so grateful to our friends and customers that deploy our fuel systems for drag racing, sled pulling, and dyno competitions. After all, we’re gearheads ourselves!
And while our primary purpose will always be saving our customers money while getting more from their trucks, we also happen to excel and building high-flow fuel systems. From bone-stock trucks to 3,000+ horsepower dedicated race trucks, there’s no diesel engine we cannot fuel.
Early on, our customers began utilizing our fuel systems in competitive applications to support horsepower levels beyond what the stock lift pump was designed for. As diesel performance has evolved, we’ve designed bigger, better fuel systems to support the demands of competition.
Currently, we offer a massive variety of fuel system options for stock and modified diesel trucks. From fueling a completely factory LBZ Duramax to a 2,500+ horsepower 6.7 Cummins, we do it all.
So is FASS a maintenance item or a performance product?
In truth, our fuel systems provide multiple benefits. Whether you’re looking to extract every MPG out of your daily driver, make your injectors last longer, or set a new horsepower record, a FASS Fuel System will help you get there.
Properly filtering fuel is always a good idea—regardless of what you use your truck for. But, if you’ve got performance in mind, rest assured we have your back too.
So, while the majority of our customers drive stock or nearly-stock diesel trucks, and benefit the most from our filtration—we will always support the performance community with the best possible products.
