While the OE diesel fuel filters in your truck might be considered adequate by some, there are other enthusiasts who are always looking for something better. Luckily, Fass Fuel Systems delivers something better. Take for instance the latest in filtration and water separation, the Drop-In Series.

Many truck owners feel they do not need a performance-oriented lift pump system. However, they are looking for better fuel filtration, and the Drop-In Series might be the perfect option. The FASS Drop-In Series was engineered to be the most effective filtration solution for your Ford, GM, or Ram truck. Backed by a limited lifetime warranty, the Drop-In Series protects your engine from the issues caused by fuel contamination.

Without proper fuel filtration, modern diesel injection systems are prone to excessive wear, which can be costly to repair. The Fass Drop-In System removes 99 percent of the water from your diesel fuel, along with entrained air and debris down to 2 Microns, the Drop-In Series System protects the injection system from premature failure.

The Drop-In series is designed for filtration only. It is not a performance lift pump.

Additionally, by eliminating the contaminants mentioned above, the Drop-In System can help optimize fuel mileage, restore horsepower, and sharpen throttle response. Fass states this system can be installed in an hour or less and is a true plug-and-play system. It requires no cutting, wiring, or additional modifications.

Industry-leading water removal capabilities (third-party proven to exceed 99 percent) are reinforced by the unique design of the Extreme Water Separator (XWS). If the XWS reaches capacity, it acts as a dam, shutting down your truck and preventing major destruction of fuel system components.

The FASS Drop-In diesel fuel filter’s design was developed to achieve great filtration with the simplest possible installation—making the Drop-In System 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. If you are looking for better diesel fuel filters that are much easier to change, check out the Fass Drop-In Series.
