Sierra 18-7289 Fuel Pump, Replaces 982997, for GM V-6 262/4.36 OMC Sterndrive/Cobra

The Sierra 18-7289 is a mechanical fuel pump built for GM V-6 262/4.36 marine engines used in OMC Sterndrive/Cobra applications. It mounts at the flange (Flange I.D. #60201) and comes with a mounting gasket included, so it is ready to install without sourcing a separate gasket. The pump body is constructed of alloy steel and aluminum for durability in a marine engine bay, and it uses a barb-style outlet connection with tank mounting.

This pump directly replaces OEM number 982997, making it a straightforward swap for boats originally equipped with that part. It is designed to move fuel reliably from the tank to the carburetor on GM V-6 262/4.36 powered sterndrive engines, restoring proper fuel delivery pressure and volume when an original pump has failed or is showing signs of wear such as leaking, weak flow, or diaphragm failure.
