Built around a 1\/4 inch (6.4mm) aluminum tall-filter housing, the kit uses a 10 micron filter element that is over 90% efficient at removing particles as small as 10 microns, while removing over 99.8% of emulsified water from the fuel before it reaches the engine. Rated to flow up to 90 gallons per hour, the filter is sized to keep pace with high-demand fuel-injected motors without restricting flow. It is designed for use on inboard, sterndrive, and outboard fuel-injection systems and is cross-referenced to multiple Mercury Marine fuel-water separator part numbers, making it a straightforward replacement where those numbers are specified.\u003c\/p\u003e\u003cp\u003eThe line is offered in two configurations. The standard kit (18-7982-1) includes one 10 micron aluminum filter element (18-7945) and a mounting base (18-7853-1), giving you everything needed for a complete first-time installation or full kit replacement. The filter with bonus pack (18-7982-2) adds a second, spare filter element on top of the same core kit, so you have a ready replacement element on hand for the next service interval without ordering separately.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7982\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Micron Rating:\u003c\/strong\u003e 10 Micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Size:\u003c\/strong\u003e 1\/4 inch (6.4mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Style:\u003c\/strong\u003e Tall Filter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Flow Rate:\u003c\/strong\u003e 90 gallons per hour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Removal Efficiency:\u003c\/strong\u003e Removes over 99.8% of emulsified water from gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eParticle Filtration Efficiency:\u003c\/strong\u003e Over 90% efficient at removing particles as small as 10 microns\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Service Type:\u003c\/strong\u003e Boat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal fit for gasoline fuel-injected engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury 35-802893A4, 35-60494A4, 35-807172A4, 35-60494A1, 35-57250A1, 35-55501A1, 35-52456A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.36 pounds (Standard Kit); 1.08 pounds (Filter with Bonus Pack)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e 1 x 18-7945 filter element and 1 x 18-7853-1 mounting base (Standard Kit); adds a second spare filter element (Filter with Bonus Pack)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eBoth options share the same 1\/4 inch aluminum, 10 micron filter and mounting base.
