It is engineered as a direct match to the original equipment pump it replaces, with a flange I.D. Of M60315 that lines up with the factory mounting pattern so installation follows the same bolt pattern and fuel line routing as the original unit.\u003c\/p\u003e\u003cp\u003eThis pump pairs with Sierra filter 18-7860 and gasket 18-0889 for a complete fuel system service, and a mounting gasket is included with the pump itself so the housing seals correctly against the engine block on installation. The housing has a machined finish and a white exterior finish. As a direct-fit replacement, the 18-7284 is intended for boat owners and marine mechanics servicing GM-based inboard and stern drive engines where the factory fuel pump has worn out or failed and needs to be swapped for a like-for-like unit.\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 18-7284\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange I.D.:\u003c\/strong\u003e M60315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Filter:\u003c\/strong\u003e 18-7860\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Gasket:\u003c\/strong\u003e 18-0889\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999322555\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eGM 4 \u0026amp; 6 Cyl.: 153, 181, 225, 250, 120, 140, 160, 165, 470, 485, 488\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e41141A2\u003c\/li\u003e\n\u003cli\u003e862077A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7284 fuel pump fit?\u003c\/strong\u003e The 18-7284 fits GM 4 and 6 cylinder engines including the 153, 181, 225, and 250 cubic inch displacement blocks, as well as the 120, 140, 160, 165, 470, 485, and 488 model families.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-7284 replace the OEM fuel pump directly?\u003c\/strong\u003e Yes, part number 18-7284 is a direct replacement matching flange I.D.
