Sierra 18-7815 Fuel Pump Kit for Mercury/Mariner Outboard Motors, Replaces Mercury Marine 1399-5137

The Sierra 18-7815 Fuel Pump Kit is a replacement fuel pump built for Mercury and Mariner outboard motors. It is engineered to meet the fuel delivery demands of high-horsepower outboard engines while standing up to the harsh marine environment, and it meets or exceeds the performance of the original equipment part it replaces.

The pump body is constructed of aluminum for corrosion resistance and durability in marine use. It uses a hose barb inlet connection and a 3/8 NPT threaded outlet connection, along with quick connect fittings for a secure, leak-resistant hookup during installation. The kit is designed as a vehicle-specific fit for Mercury/Mariner outboard motor applications and is offered as a direct equivalent to Mercury Marine part number 1399-5137.

Sierra supplies fuel pump kits and other engine components to OEM engine manufacturers and boat builders, and the 18-7815 is backed by Sierra's limited warranty.
