Product Description

The Fuelab 81811-1 is a compact 818 Series inline fuel filter featuring -6AN male inlet and outlet ports with a 3-inch 40 micron stainless steel mesh element. The stainless steel element is cleanable and reusable, making it a cost-effective long-term option for performance fuel systems or as a pre-filter ahead of a finer post-pump filter. At 200 GPH flow capacity and 200 PSIG maximum pressure, it handles the demands of most EFI and carbureted performance builds.

The billet aluminum body is machined with internal radii to minimize pressure drop and finished in black anodize to military spec. Male -6AN / 37° flared end caps allow direct integration with standard AN fuel line fittings, and the machined hex on the outer sleeve simplifies disassembly for element service. Compatible with gasoline, diesel, methanol, and ethanol. The -1 suffix designates the black anodized finish.
