Fuelab 85802-1 Series In-Line Fuel Filter Long Micron with Check Valve - 858 10

The Fuelab 858 Series In-Line Fuel Filter (85802-1) combines a high-quality 10-micron replaceable fabric filter element with an integrated check valve in a single, compact unit. The integrated check valve allows your fuel system to maintain fuel pressure after engine and pump shutdown — eliminating the need for a separate check valve component and the additional fittings required to install one.

Key Features:

• 10-Micron Replaceable Fabric Element — long-length, 5-inch element size for high flow capacity and easy maintenance
• Integrated Check Valve — maintains fuel system pressure after engine and pump shut down
• Broad Fuel Compatibility — check valve and filter are compatible with gasoline, diesel, ethanol (E85), and methanol fuels
• All-in-One Design — check valve is protected inside the filter housing, reducing plumbing complexity and potential leak points
• Long-Length Housing — provides increased filter media surface area for extended service intervals

The Fuelab 85802-1 is an ideal solution for performance, racing, and alternative-fuel applications where maintaining residual fuel pressure and fuel purity are critical. The replaceable element design keeps long-term maintenance costs low without requiring full filter replacement.
