The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most cost effective and easiest solution to remove air vapor and entrained air from your diesel fuel in your Cummins ISX and X15 fuel system.

By removing the entrained air and air vapor, the Drop-In Series System protects diesel injection systems from premature failure and can triple the life of your fuel injection system!

Additionally, by eliminating the contaminants mentioned above, our Universal Drop-In Series System for virtually any diesel engine platform optimizes MPG (results will vary), restores horsepower, and sharpens throttle response.

And if reliability, optimized MPG, restored horsepower, and a sharper throttle response isn't enough, this system can be installed in an hour or less! This is a true plug-and-play system, requiring no cutting, wiring, or additional modifications.

FASS Drop-In Technology was developed to achieve industry-leading filtration with the simplest possible installation, making our Drop-In Series Systems a true bolt-in upgrade. If you're mechanically inclined, a Drop-In Series Fuel System can be installed in your driveway in less than an hour!
