Fuelab 85801-6 Series Long Length In-Line Fuel Filter with Integrated Check Valve Micron - 858 10

The Fuelab 85801-6 is a long-length, high-flow inline fuel filter from the 858 Series, featuring a fully integrated check valve assembly and a 10-micron replaceable fabric element. Designed for performance and race fuel systems, this filter keeps fuel clean while simultaneously maintaining fuel pressure after engine and pump shutdown — all in a single, compact unit.

The integrated check valve eliminates the need for a separate component and additional fittings. Because the check valve is housed within the filter body, it is protected from contamination and damage. This two-in-one design simplifies installation and reduces potential leak points in your fuel system.

Key Features:

• Integrated check valve maintains fuel pressure after engine and pump shutdown
• Helps prevent vapor buildup in fuel rails during engine cool-down
• Long length (5-inch element) for increased filtration and flow capacity
