It uses a durable plastic outer housing and is designed as a direct replacement for the OEM fuel filters used by Mercury Marine and OMC-equipped outboards, making it a straightforward swap during routine fuel system maintenance. The filter is intended to protect carburetors and fuel injection components from debris and contaminants in the fuel line, helping maintain consistent fuel flow and engine performance.\u003c\/p\u003e\u003cp\u003eThis filter is cross-referenced to several widely used aftermarket and OEM part numbers, so it is compatible with equipment originally fitted with Fram, GLM, Mallory, OMC, or Wix filters bearing the matching part numbers listed below. Each unit ships as a single filter (1 count) ready for installation in the fuel
