Fuelab 84811-1 Series Inline Fuel Filter with Check Valve Micron Stainless Steel - 848 40 6AN

The Fuelab 84811-1 is a standard-length, high-flow inline fuel filter from the 848 Series, featuring a 40-micron cleanable stainless steel element and an integrated check valve — all housed in a single billet aluminum assembly. Designed for performance fuel systems, this filter helps maintain fuel pressure after engine and pump shutdown, reducing the risk of vapor buildup in the fuel rails during engine cooling.

By integrating the check valve directly into the filter housing, Fuelab eliminates the need for a separate check valve component, additional fittings, or adapters. The check valve assembly is also shielded from contamination by the filter element itself, extending its service life and reducing overall maintenance requirements.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• 40-micron stainless steel element — cleanable and reusable, ideal for racing and high-demand applications
• Standard length with 3-inch filter element for greater flow and filtration capacity
• -6AN male inlet and outlet for direct connection to AN-compatible fuel system components
• Billet aluminum housing with military-spec Type II anodize (MIL-A-8625) for durability and corrosion resistance
• Machined internal radii for minimal pressure drop across the filter
• 200 PSIG maximum pressure rating — suitable for high-pressure fuel injection systems
• Compatible with gasoline, diesel, methanol, and ethanol fuel types
• Includes low-profile saddle clamp mounting bracket
• Supports up to 200 GPH flow capacity
• Backed by a limited lifetime warranty

The 848 Series inline fuel filter is sold individually and is available in multiple anodized colors. The stainless steel element is cleanable and does not require replacement for routine maintenance, making it a cost-effective long-term solution for performance and racing fuel systems.
