Indepth details on How air in fuel negatively affect your engine’s performance
With the longer burn discussed under “Increased Horsepower and Torque” a fuel mileage increase is “AVAILABLE” due to the simple fact there is now a more complete combustion, therefore, needing less fuel to perform the same task

FASS Diesel Fuel Systems are the number one preferred Fuel Air Separation System selected for use by fleets & owner operators worldwide. FASS System are designed not only to eliminate inconsistent engine performance, which consist of not just torque/power but fuel economy, idle quality, throttle response and how the engine just sounds. Have you ever noticed how much better the engine performs with a full tank of coll fuel that hasn't been traveling down the road long vs. a quarter tank of hot fuel that has been agitating all day? A truck with full tank of cool fuel that has been subjected to less agitation performs much better. The FASS System will keep it like the full tank of cool fuel but will allow it to perform better all day, much more consistent. The dause of this inconsistency is fuel starvation, air & vapor! Delivering purified fuel without this Air & Vapor not only takes care of this inconsistent performance but also increases the life of the fuel injection system.
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.

Calculate Your Fuel savings
Throughout this guide, we’ll be referencing documents from manufacturers such as Bosch, Caterpillar, Cummins, Detroit
Diesel & Racor/Parker just to name a few. We’ll be covering their findings on how air & vapor develop and how it affects
the dependability of your injectors and engine performance.
