Fuelab 84811-3 Series In-Line Fuel Filter Micron with Check Valve - 848 40 Stainless Blue

The Fuelab 84811-3 is a 848 Series standard-length in-line fuel filter featuring a 40-micron stainless steel element and an integrated check valve, finished in a blue anodized billet aluminum housing. Designed for high-performance fuel systems, this filter maintains fuel pressure after engine and pump shutdown while protecting the check valve assembly within the same housing — eliminating the need for separate components and additional fittings.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown, helping prevent vapor buildup in fuel rails during engine cooling
• 40-micron stainless steel filter element — cleanable and reusable, designed for harsh racing conditions and broad fuel compatibility
• Billet aluminum housing with military-grade anodized finish (MIL-A-8625, Type II) in blue
• Machined internal radii for minimal pressure drop across the filter
• -6AN male inlet and outlet end caps for direct connection to AN fuel system components
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
• Compatible with gasoline, diesel, ethanol (E85), and methanol fuels
• Includes low-profile saddle clamp mounting bracket
• 3-inch element size, standard length
• Backed by a 2-year limited warranty

The 848 Series integrated filter and check valve design simplifies fuel system builds by combining two critical components into one compact, serviceable unit. The stainless steel element can be cleaned rather than replaced, reducing long-term maintenance costs and downtime.
