The FASS Drop-In Series Diesel Fuel System was engineered by FASS to be the most cost-effective and easiest solution for removing air vapor and entrained air from diesel fuel. In addition to advanced air separation, this universal system features high-capacity particulate filtration down to 2 micron absolute.

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

Eliminating these contaminants helps optimize MPG (results will vary), restore horsepower, and sharpen throttle response. This universal kit can be adapted to nearly any diesel application.

Reliability. Simplicity.

Protection. Injector Protection: Triples the life of injectors and injection pumps.

FASS Filtration: Optimizes combustion, restores horsepower, and maximizes MPG (results vary). Limited Lifetime Warranty: Register your FASS system and you're covered.

Advanced In-Tank Filtration Technology

Fits: Universal Diesel Applications

The FASS Drop-In Series focuses on fuel quality:

• Air and Vapor Removal: Eliminates entrained air and vapor that damage injection systems and reduce efficiency
• 2 Micron Absolute Filtration (Microglass): Removes debris smaller than OEM filters can capture

Key Benefits:

• Improves Reliability: Extends injection system life up to 3x
• Maximized Horsepower: Improved fuel atomization and restored injection timing for a smoother, more balanced engine
• Optimized MPG: More efficient and complete combustion (results will vary)
• Extreme Cold Weather Confidence: Reliable starts and operation in harsh climates, especially when paired with the FASS Drop-In Fuel Heater Kit
• Cleaner Operation: Reduced DPF regenerations and soot output through improved combustion
