Description
Overview
The FASS Fuel Systems Drop-In Series Fleet Filter Pack (Part Number FLP1000) is a complete filtration bundle built to keep your FASS Fuel Drop-In System running clean between service intervals. Designed for the shop or for keeping your home garage stocked, this diesel fuel filter kit takes the guesswork out of your next fuel filter replacement by pairing the exact filters your Drop-In system needs in one convenient pack.
Each pack contains two (2) XWS3002XL Extreme Water Separator Filters and two (2) CWS1010 Coalescing Water Separator (Drop-In) Filters. Together, these filters work as a system: the Extreme Water Separator element pulls damaging water and contaminants out of your diesel, while the coalescing filter finishes the job to help protect your injection system. On RAM and Ford Drop-In units, the CWS1010 must be used in conjunction with the XWS3002XL Extreme Water Separator Filter — the two are engineered to operate as a matched set.
Key Benefits
Stocking a Fleet Filter Pack means you’re always ready when it’s time to change the fuel filter, whether you run a single truck or manage a fleet. Because everything you need for two full service cycles is included, changing your fuel filter is faster and easier, and you avoid the hassle of tracking down separate part numbers. Convenience is built in from the start, with clear guidance on filter placement so installation goes smoothly.
