Enhancing Engine Longevity


FASS Contaminant Removal

Lancaster, PA FASS Dealer - GMK Mechanical Diesel is about power. And no matter what job your equipment does for you, your power and efficiency start with pure clean fuel so, your improvements should start with FASS.

Here’s why:

Water, Dirt, Air and Vapor. They contaminate diesel fuel, Which will reduce engine performance! When fuel passes through the stock filter, it breaks large air bubbles into smaller ones, but they still get through and air still reaches your injection components.

With air in the injector tip, there is no fluid damping, which allows the plunger to impact the tip with up to 50% greater force which leads to cracked injector tips or even worse, tips that are broken off into the cylinder. Plus, the presence of air reduces lubrication by at least 10%, which causes galling and scoring. When combined with high pressure in fuel, the injector orifice is exposed to a cutting torch effect, damaging your injectors even more. This air can also retard the timing of your injectors, leaving less time for the fuel to properly atomize across the piston, and causing more heat concentration that will damage your pistons.

FASS removes these contaminants. This reduces the wear of your expensive fuel injection components to keep your equipment operating longer. The FASS process begins way ahead of conventional fuel systems. Entering under a vacuum and exiting under pressure, FASS removes dirt and debris before fuel enters the electric fuel pump. Next, fuel then enters the high-efficiency Extreme Water Separator. Here, FASS traps and removes 99.96% of the water molecules. Air and vapor are then returned back to the fuel tank. Exclusive performance radius cuts create the smoothest path to your injectors. The mass flow return continually polishes the fuel making FASS second to none in regard to achieving the cleanest possible fuel being delivered to your diesel engine period!

Powering Performance with Purity in Extreme Conditions

Lancaster, PA FASS Dealer - GMK Mechanical The continual fuel polishing combined with our optional fuel heaters makes FASS the industry leader when it comes to extreme cold weather performance.

It’s also quieter. Our Revolutionary Whisper Technology makes it the quietest fuel air separation system in the world. By delivering pure fuel without contaminants, FASS creates a longer, cleaner burn, and the proper atomization of fuel across the piston reduces regens.

This process holds the manufacturers’ timing specifications, which significantly improves power output. Plus, greater fuel efficiency in your diesel engine means better performance of your equipment.

FASS gives you more power and efficiency by removing all types of fuel contaminants and delivering the purest fuel available to your diesel engine!
