Overview

The Fleetguard FS1022 Fuel Filter comes in a convenient pack of two, designed to support clean, reliable fuel delivery in diesel engines. Built to align with Cummins 3800394 applications, this filter also cross-works with common replacements such as Donaldson P551003 and Fleetguard FS1003. While individual results vary by vehicle and operating conditions, the FS1022 is built to help maintain fuel cleanliness and consistent flow when properly installed and maintained.

Crafted for demanding service, this two-pack is well suited for fleets, long-haul applications, and daily workloads where fuel quality and system reliability matter. The kit’s thoughtful engineering aims to fit securely, minimize leaks, and integrate smoothly with existing fuel lines and mounts.
