It draws fuel from the tank and delivers it to the carburetor or fuel injection system at the pressure and volume the engine's fuel delivery design requires, replacing a worn or failed factory pump with a unit built to original equipment specification.\u003c\/p\u003e\u003cp\u003eThe pump body is aluminum for corrosion resistance in a marine engine compartment, and it uses a tank-mount configuration with mechanical (non-electric) operation. Both the inlet and outlet connections are 1.13 inch hose barb fittings, matching the fuel line routing on applicable MerCruiser 502 cid V-8 engines. It is designed as a direct fit for the specific engine\/serial number ranges listed below, so confirming your engine model and serial number before ordering ensures correct fitment.\u003c\/p\u003e\u003cp\u003eThis is a straightforward mechanical replacement part with no electronic components to program or calibrate, making it a common service item for engine maintenance and fuel system troubleshooting on covered MerCruiser 8.2L applications.\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 18-8860\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Marine Fuel Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e Mechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Tank Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Type:\u003c\/strong\u003e Hose Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection Size:\u003c\/strong\u003e 1.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Type:\u003c\/strong\u003e Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Connection Size:\u003c\/strong\u003e 1.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4.6 x 6.9 x 5.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.82 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282294724\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser 8.2L MIE 502 cid V-8, 1993-1996, engine serial number D857200 through F819619\u003c\/li\u003e\n\u003cli\u003eMerCruiser 8.2L MPI MIE 502 cid V-8, 1996-1997, engine serial number F819620 through K147349\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-8860 fuel pump fit?\u003c\/strong\u003e The Sierra 18-8860 fits MerCruiser 8.2L MIE 502 cid V-8 engines built in the 1993-1996 range with engine serial numbers D857200 through F819619, and MerCruiser 8.2L MPI MIE 502 cid V-8 engines built in the 1996-1997 range with engine serial numbers F819620 through K147349.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this fuel pump mechanical or electric?\u003c\/strong\u003e The 18-8860 is a mechanical fuel pump, meaning it is driven off the engine rather than powered electrically.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I confirm the 18-8860 is correct for my boat?\u003c\/strong\u003e Check your MerCruiser engine's serial number against the covered ranges: D857200-F819619 for the 8.2L MIE 502 V-8, or F819620-K147349 for the 8.2L MPI MIE 502 V-8.
