It is a rotary vane style pump with an aluminum body, designed to meet or exceed original equipment quality so it draws fuel from the tank and delivers it to the carburetor at the pressure and volume the powerhead needs to run correctly. Both the inlet and outlet connections are threaded for a secure, leak-resistant fit to the factory fuel lines.\u003c\/p\u003e\u003cp\u003eThis pump is a direct replacement for a worn or failing OEM unit, correcting symptoms like hard starting, stalling at idle, hesitation under load, or inconsistent fuel delivery caused by a weak diaphragm or worn vanes in the original pump. It is a tank-mounted unit with a mechanical operating mode, matching the factory arrangement on these outboards, so no rewiring or electrical fuel system changes are needed. As a genuine Sierra part, it carries Sierra's standard customer satisfaction warranty.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
