Fuelab 84801-6 Series In-Line Fuel Filter with Integrated Check Valve Micron - 848 10 6AN

The Fuelab 84801-6 is a standard-length, in-line fuel filter from the 848 Series, featuring a -6AN male inlet and outlet, a 10-micron replaceable cellulose (paper) element, and a factory-integrated check valve — all in a single billet aluminum assembly.

The integrated check valve helps your fuel system maintain pressure after engine and pump shutdown, and prevents vapor buildup in the fuel rails during engine cooling. By combining the filter and check valve into one unit, the check valve is shielded from contaminants and debris by the filter itself — eliminating the need for extra fittings or separate components. The 10-micron paper element is the most economical and commonly used option, offering excellent filtration performance in a disposable, replaceable format.
