Sierra 18-7266 Fuel Pump with Mounting Gasket for Ford V-8 302 and 351 Engines

The Sierra 18-7266 is a flange-mount fuel pump built for Ford V-8 302 and 351 marine engines. It arrives complete with a mounting gasket so it can be installed directly onto the engine's fuel pump flange without sourcing a separate gasket. The pump body is constructed of aluminum alloy for corrosion resistance and long service life in a marine environment, and it uses a flange-type inlet connection paired with an NPT outlet connection for compatibility with standard fuel line fittings.

This pump is designed as a direct replacement for the original equipment fuel pump on Ford V-8 302 and 351 marine engines, including Ford, MerCruiser, and Commander applications built around this engine family. Sierra manufactures the 18-7266 to meet or exceed the performance of the original equipment part it replaces, making it a straightforward swap for a worn or failing OEM pump. The flange identification numbers for this pump are 41413 and M6696, which can be used to confirm a correct match against the fuel pump flange on the engine before ordering.
