Overview

Catalog code AI-FS1003J identifies this unit within Fleetguard's filtration lineup, reflecting a rugged, field ready design built for fleet service.

Key Benefits

How It Works

  • Marine, agricultural, and off road machines that rely on clean fuel delivery.

Maintenance Tips

  • Replace at the recommended service interval or when performance is affected.
