At the 2026 Mid-America Trucking Show (MATS), we had the opportunity to sit down with one of the most respected names in the diesel industry: Mario Monette, owner of
Mario High Performance Diesel (MHPD).
In this testimonial interview, Mario joins Jeremy Murders, COO of FASS Diesel Fuel Systems, to discuss his real-world experience using, selling, and installing FASS systems across everything from working trucks to extreme high-horsepower builds.
The full interview video is embedded below.
For years,
Mario High Performance Diesel has been a major force in the trucking and heavy-duty diesel world. Known for advanced diesel tuning and performance development, MHPD has built a reputation for creating some of the most powerful diesel trucks on the planet.
That includes Mario’s legendary drag truck:
“The Beast”
This incredible machine utilizes:
- Four (4) FASS 540GPH Competition Series Fuel Systems

4,000 horsepower (true horsepower remains unknown)
At that level of performance, fuel supply and filtration are absolutely critical—and that’s exactly why FASS systems are part of the combination.

Throughout the interview, Mario discusses:
- Why MHPD trusts FASS products
- His experience installing FASS systems
- The importance of fuel quality and consistency
- How FASS systems perform in both street and competition environments
