Fuelab 84812-4 848 Series In-Line Fuel Filter -8AN 40 Micron Stainless Steel with Check Valve Green

The Fuelab 848 Series In-Line Fuel Filter (84812-4) combines high-performance fuel filtration with an integrated check valve in a single, compact billet aluminum housing. Featuring -8AN male inlets and outlets and a 40-micron stainless steel mesh element, this standard-length filter is built for high-performance fuel systems demanding reliability and clean fuel delivery.

The integrated check valve allows the fuel system to maintain fuel pressure after engine and pump shutdown, helping to prevent vapor buildup in fuel rails during engine cooling — eliminating the need for a separate check valve component and additional fittings. The stainless steel mesh element is cleanable and reusable, reducing long-term maintenance costs.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• 40-micron stainless steel mesh element — cleanable and reusable, no replacement required for routine maintenance
• -8AN male inlet and outlet fittings for direct connection to AN fuel system components
• Billet aluminum housing with military-spec Type II anodized finish (MIL-A-8625) in green
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• Machined internal radii for minimal pressure drop
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
• 3-inch element size; standard (short) body length

The Fuelab 84812-4 is an ideal solution for performance street and race fuel systems looking to consolidate filtration and check valve functions into one protected, serviceable assembly.
