Fuelab 81813-5 Series In-Line Fuel Filter Micron - 818 40 Stainless Steel 10AN

The Fuelab 81813-5 is a compact 818 Series in-line fuel filter featuring a 40-micron stainless steel filter element designed for high-performance and racing fuel systems. Built from billet aluminum with a military-grade Type II anodized finish (MIL-A-8625), this filter delivers reliable filtration while withstanding the demands of aggressive fuel system environments. The 3-inch element housing measures 4.33" in overall body length with a 2.13" diameter.

Machined internal radii minimize pressure drop across the filter, and the male AN / 37° flared fitting end caps allow direct connection to AN female-ported fuel system components. The 40-micron stainless steel element is compatible with gasoline, diesel, methanol, and ethanol fuels, making it an ideal choice for both street and competition builds. The element is cleanable and does not necessarily require replacement during routine maintenance.
