Sierra 18-7284 Fuel Pump for GM 4 & 6 Cyl 153/181/225/250 Engines, Replaces 41141A2, 862077A1

The Sierra 18-7284 is a marine fuel pump built to deliver reliable fuel supply on GM 4 and 6 cylinder inboard 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. 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.

This 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.
