Sierra Fuel Pump 18-7288-1 - Replaces 41141A2, 862077A1 - Fits GM V-6 231, 262, 229

The Sierra 18-7288-1 is a replacement mechanical fuel pump built for GM (V-6) 231, 262, and 229 cubic-inch marine engines. It is designed as a direct swap for the original equipment pump on these engine blocks, delivering fuel from the tank to the carburetor at the pressure and volume the engine was designed around. A mounting gasket is included so the pump can be installed and sealed against the engine block without sourcing a separate gasket.

For continued servicing, Sierra recommends pairing this pump with fuel filter 18-7784 and gasket 18-0889 to keep the fuel delivery system sealed and filtered. The pump carries the Manufacturer Part Number 18-7288-1 and cross-references directly to OEM numbers 41141A2 and 862077A1, so it is a straightforward like-for-like replacement for boat owners whose original pump has failed or is showing signs of wear such as inconsistent fuel pressure or fuel leakage at the mounting flange.
