What is FASS
FASS Diesel Fuel Systems are the #1 Fuel/Air Separation System for fleets & owner-operators worldwide. FASS Diesel Fuel Systems are designed to optimize engine performance–including torque/power, fuel economy, idle quality, throttle response & more.
Have you noticed how much better the engine performs with a full tank of fresh, cool fuel when compared to a 1/4 tank of hot fuel that’s been agitating all day? It goes without saying that a truck full of cool fuel performs much better.
By keeping your engine supplied with fresh, polished fuel, your truck stays at peak performance–day in, day out. With a FASS, you can say goodbye to the days of inconsistent performance caused by fuel starvation, air & vapor! Delivering purified fuel without air & vapor not enhances performance, but also increases the life of the fuel injection system.
Fuel Mileage Testing Results
1 – Hour Dyno Test Completed Using Cat C15 Engine Certified third party test – Realworld Conditions will vary.
We understand that a class 8 truck doesn’t average 75mph and probably doesn’t average 58% work load in most areas. But they do average around 125,000 miles per year. If we use those calculations from the Caterpillar dyno test with the stock fuel filter the engine got 3.15mpg and with the FASS got 3.76mpg. an increase in fuel mileage of 0.61mpg. This is interesting as we tell potential customers that there is a solid 0.4mpg to be had, however on this engine 0.7-0.9mpg increase is not unheard of. So let’s go to the conservative numbers of 0.4mpg.
