Fuelab 84832-3 848 Series In-Line Fuel Filter with Check Valve 6 Micron Fiberglass -8AN Purple

The Fuelab 848 Series In-Line Fuel Filter (84832-3) combines a high-performance inline fuel filter and integrated check valve into a single, compact billet aluminum unit. The integrated check valve allows your fuel system to maintain fuel pressure after engine and pump shutdown, while also helping to prevent vapor buildup in your fuel rails during engine cooling cycles.

This filter features a 3-inch, 6-micron micro-fiberglass element — Fuelab's most advanced filter media — delivering superior particle protection and extended service intervals compared to standard paper elements. The disposable element is not cleanable and should be replaced at each service interval. The check valve is fully compatible with gasoline, diesel, methanol, and ethanol fuels, including E85 applications.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• 6-micron micro-fiberglass element for maximum particle filtration efficiency
• 3-inch standard-length element for compact installation
• Billet aluminum housing with military-spec anodized finish (MIL-A-8625, Type II)
• -8AN male inlet and outlet fittings for direct AN plumbing integration
• Machined internal radii for minimal pressure drop across the filter
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
• Compatible with gasoline, diesel, methanol, and ethanol (E85)
• Includes low-profile saddle clamp mounting bracket
• Backed by a limited lifetime warranty

By combining the filter and check valve into one assembly, the check valve is shielded from contaminants and debris, eliminating the need for additional fittings or adapters. The 84832-3 features a purple anodized finish and is sold individually.
