The Fuelab 85801-5 is a long-length, in-line fuel filter from the 858 Series, featuring a 10-micron replaceable fabric element and an integrated check valve. This all-in-one design allows your fuel system to maintain fuel pressure after engine and pump shutdown — eliminating the need for a separate check valve component and the extra fittings required to adapt it.
