The air trapped in your fuel (diesel is at least 10% when stationary, per CAT) costs you money. Air/vapor in fuel reduces power, MPG, and can ultimately lead to expensive injection system repairs. By eliminating the air and vapor from your fuel, our Drop-In Series System restores horsepower, optimizes MPG, sharpens throttle response, and delivers a smoother idle. The best part? This system is VERY affordable, and installs in 15 minutes or less! | FASS Fuel Systems
