How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

Description

Fits: 3406E, C10, C11, C12, C13, C15, C16, and C18 Caterpillar Engines Equipped with 1R-0749 and 1R-0750 Fuel Filters 

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 Caterpillar fuel system.

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

Additionally, by eliminating the contaminants mentioned above, our Drop-In Series System for the Caterpillar 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!
