Fuelab 85802-3 858 Series In-Line Fuel Filter with Integrated Check Valve -10AN Long Length Green

The Fuelab 85802-3 is a long-length, high-flow in-line fuel filter from the 858 Series, featuring an integrated check valve in a green anodized billet aluminum housing. Designed for performance fuel systems, this filter maintains fuel pressure after engine and pump shutdown while simultaneously protecting the check valve assembly from contaminants — eliminating the need for a separate check valve and additional fittings.

The integrated check valve prevents fuel vapors from building up in the fuel rails during engine cooling cycles, improving hot-start reliability and fuel system stability. The 10 micron replaceable fabric element captures harmful particles before they can reach injectors or carburetors, and can be swapped out for servicing without replacing the entire unit.

Key Features:

• Integrated check valve — maintains fuel rail pressure after shutdown and prevents vapor buildup
• 10 micron replaceable fabric element — serviceable without full unit replacement
• Long-length 5-inch element — greater filtration capacity and reduced maintenance frequency
• -10AN male inlet and outlet — direct connection to AN-compatible fuel system components
• Up to 200 GPH flow capacity — suitable for high-performance and forced-induction applications
• 200 PSIG maximum pressure rating — compatible with high-pressure fuel systems
• Billet aluminum housing with military-spec MIL-A-8625 Type II green anodized finish
• Machined internal radii for minimal pressure drop through the filter body
• Gasoline, diesel, methanol, and ethanol compatible
• Includes low-profile saddle clamp mounting bracket
• Backed by a limited lifetime warranty

The Fuelab 858 Series is available in multiple element micron ratings and six anodized color options to match your build. The 85802-3 is the green-sleeve variant with a 10 micron fabric element and -10AN fittings.
