Sierra 18-7282 Fuel Pump for GM 4 Cylinder 2.5L/3.0L and Mercruiser 3.7L Engines, Replaces 8M0073435

The Sierra 18-7282 is a marine fuel pump built for GM 4 cylinder (2.5L/3.0L) and Mercruiser 3.7L engines. It mounts using flange I.D. Number M60337 and is designed to move fuel from the tank to the carburetor or throttle body at the pressure and volume these engines require for reliable running. As an aftermarket fuel pump, the 18-7282 is a direct equivalent to the original equipment pumps used on these applications, giving boat owners and marine technicians a replacement option when the factory pump fails, weakens, or starts causing hard starting, stalling, or inconsistent fuel delivery.

The pump pairs with two other Sierra service parts for a complete fuel system service: filter 18-7784 and gasket 18-0889. Replacing the pump along with a fresh filter and a new mounting gasket at the same time helps ensure a proper seal and consistent fuel flow, and is good practice any time a fuel pump is serviced. The 18-7282 directly replaces OEM numbers 8M0073435 and 861676T09, so it can be ordered by either the OEM number or the Sierra part number 18-7282 with confidence that it is the correct fit for GM 4 cylinder 2.5L/3.0L and Mercruiser 3.7L marine engines.
