Fuelab 84812-2 Series In-Line Fuel Filter Micron Stainless Steel with Check Valve - 848 8AN 40 Red

The Fuelab 848 Series In-Line Fuel Filter (84812-2) combines a high-flow inline fuel filter and an integrated check valve into a single compact unit. With -8AN male inlet and outlet fittings and a 40-micron stainless steel filter element, this standard-length filter is engineered for performance fuel systems that demand reliability and clean fuel delivery.

The integrated check valve keeps fuel pressure stable after engine and pump shutdown, helping to prevent fuel vapors from building up in the fuel rails during engine cool-down. By combining both components in one housing, the check valve is shielded inside the filter body — eliminating the need for extra fittings or separate check valve adapters. The red anodized billet aluminum housing is finished to military MIL-A-8625 Type II anodizing standards for exceptional durability.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• 40-micron stainless steel element — cleanable and reusable, ideal for methanol, ethanol, gasoline, and diesel
• 3-inch standard-length filter element
• -8AN male inlet and -8AN male outlet (AN 37° flared fittings)
• Machined internal radii for minimal pressure drop
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
• Billet aluminum housing with red anodized finish (MIL-A-8625, Type II)
• Includes low-profile saddle clamp mounting bracket
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• Backed by a 2-year limited warranty

The 848 Series is an ideal choice for high-performance street and race applications where fuel system integrity and compact packaging are priorities. The reusable stainless steel element reduces long-term maintenance costs, and the all-in-one filter/check valve design simplifies installation.
