Fuelab 85802-6 858 Series High-Flow In-Line Fuel Filter with Integrated Check Valve -10AN 10 Micron

The Fuelab 85802-6 is a long-length, high-flow in-line fuel filter from the 858 Series, featuring an integrated check valve, -10AN male inlet and outlet, and a 10 micron replaceable fabric (cellulose/paper) element. Designed for performance fuel systems, this filter combines two critical components into a single, compact unit — eliminating the need for separate check valve hardware and extra fittings.

The integrated check valve allows your fuel system to maintain fuel pressure after engine and pump shutdown, helping to prevent vapor buildup in your fuel rails during engine cool-down. This means faster starts and more consistent fuel delivery every time.

Key Features:

• Long-length design with 5-inch filter element for increased filtration and flow capacity
• Integrated check valve assembly — check valve is protected inside the filter body
• -10AN male inlet and outlet connections
• 10 micron replaceable cellulose (paper) element — economical and effective for daily use
• Compatible with gasoline, diesel, methanol, and ethanol fuels
• Billet aluminum housing with military-spec anodized finish (MIL-A-8625, Type II)
• Machined internal radii for minimal pressure drop
• Supports up to 200 GPH flow capacity
• 200 PSIG maximum pressure rating
• Includes low-profile saddle clamp mounting bracket
• Male AN flared fitting end caps for direct connection to fuel system components
• Backed by a Limited Lifetime Warranty

The 85802-6 is sold individually and is an ideal upgrade for high-performance street, strip, or off-road fuel systems requiring reliable filtration and sustained fuel pressure. The replaceable element design reduces long-term maintenance costs compared to disposable filter assemblies.
