It mounts to the engine block via a flange with I.D. Number 6790 and draws fuel through a mechanical, engine-driven action rather than an electric motor, matching the original factory pump arrangement used on these GM-based marine powerplants.\u003c\/p\u003e\u003cp\u003eEvery Sierra 18-7256 fuel pump ships complete with its mounting gasket, so the pump can be installed directly against the engine block without sourcing a separate gasket. The pump is built to original equipment specification and is a recognized equivalent to the Crusader 32722 fuel pump, making it suitable for boats and stern drives that were originally fitted with that pump. It carries a limited warranty from Sierra.\u003c\/p\u003e\u003cp\u003eThis pump is intended for inboard and sterndrive marine applications using the GM 4 and 6 cylinder 153, 230, 250, and 292 cid engine family. Confirm your engine's cubic inch displacement and existing flange configuration before ordering to ensure correct fitment.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-7256\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange I.D.
