Sierra Fuel Filter 18-7860, Replaces Mercury Marine 35-49088A2, for GM 4 & 6 Cylinder 153-225 cid Engines

The Sierra 18-7860 is a replacement fuel filter engineered for GM 4 and 6 cylinder marine engines, covering the 153, 181, 250, 224, and 225 cubic inch displacement range. It is built to keep contaminants out of the fuel system before fuel reaches the carburetor, protecting downstream components from debris and sediment that can cause rough running, clogging, or premature wear.

The filter housing is constructed of metal and rates at 62 microns of filtration, providing reliable screening for inline 4 and 6 cylinder engine fuel delivery. It is designed for use with AC-style fuel pumps and can be used in the 18-7278 fuel pump. For a complete seal on installation, pair the 18-7860 filter with the companion 18-0889 gasket.

As a direct fit replacement part, the 18-7860 cross-references to OEM fuel filter numbers from Mercury Marine, OMC, and Chris-Craft, making it straightforward to identify as the correct replacement regardless of which OEM number appears on your original part or parts diagram.
