Fuelab 85802-4 858 Series In-Line Fuel Filter with Integrated Check Valve -10AN 10 Micron Green

The Fuelab 85802-4 is a high-flow 858 Series in-line fuel filter featuring an integrated check valve in a long-length billet aluminum body with a green anodized finish. The built-in check valve keeps your fuel system pressurized after engine and pump shutdown, helping to prevent vapor buildup in your fuel rails during engine cool-down — eliminating the need for a separate check valve component and additional fittings.

Key Features:

• -10AN male inlet and outlet for direct connection to other AN fuel system components
• 10-micron replaceable fabric (cellulose) element — long 5-inch element for increased filtration capacity
• Integrated check valve maintains fuel pressure after engine and pump shutdown
• Supports up to 200 GPH with machined internal radii for minimal pressure drop
• 200 PSIG maximum pressure rating
• Billet aluminum construction with military-spec Type II anodized finish (MIL-A-8625)
• Compatible with gasoline, diesel, methanol, and ethanol
• Includes low-profile saddle clamp mounting bracket
• Replaceable filter element for reduced long-term maintenance costs
• Backed by a Limited Lifetime Warranty

The 858 Series combines high-flow filtration and check valve protection in a single compact unit, simplifying installation and reducing plumbing complexity for performance street and race fuel systems. The green anodized sleeve provides easy visual identification in multi-component fuel system builds.
