Fuelab 85832-4 Series In-Line Fuel Filter Long Micron Fiberglass with Check Valve - 858 6

The Fuelab 85832-4 is a long-length, 858 Series in-line fuel filter featuring a 6-micron fiberglass filter element with an integrated check valve. Designed for high-performance and racing fuel systems, this filter maintains fuel pressure after engine and pump shutdown — eliminating the need for a separate check valve component.

The integrated check valve design is a key advantage: the filter element protects the check valve from debris and contamination, extending its service life while simplifying installation. No additional fittings or adapters are required to accommodate a standalone check valve in your fuel line.

Key Features:

• 6-Micron Fiberglass Element — provides fine filtration to protect fuel system components from particulate contamination
• Integrated Check Valve — maintains fuel pressure after engine and pump shutdown for faster restarts
• Long-Length Housing — accommodates a 5-inch filter element for greater filtration capacity and longer service intervals
• Multi-Fuel Compatible — suitable for gasoline, diesel, ethanol (E85), and methanol fuel systems
• All-in-One Design — eliminates the need for a separate check valve, extra fittings, and adapters
• Part of Fuelab's comprehensive 858 Series in-line filter lineup

The Fuelab 85832-4 is an ideal solution for performance builds requiring reliable fuel pressure retention and clean fuel delivery in a single, compact inline package.
