Fuelab 84831-3 Series In-Line Fuel Filter with Check Valve Micron Fiberglass - 848 6 6AN Blue

The Fuelab 84831-3 is a standard-length, 6-micron micro-fiberglass in-line fuel filter featuring an integrated check valve — all housed in a blue-anodized billet aluminum body. By combining the filter and check valve into a single unit, the check valve assembly is protected inside the filter housing, eliminating the need for additional fittings or separate components in your fuel system.

The integrated check valve helps your fuel system maintain fuel pressure after engine and pump shutdown, and prevents vapor buildup in the fuel rails during engine cool-down — a critical advantage for high-performance and EFI fuel systems. The 6-micron micro-fiberglass element delivers superior particle filtration compared to standard paper elements, with increased filtration efficiency and reduced maintenance intervals. Note: this element is disposable and not intended to be cleaned.
