The diaphragm does all the work inside the fuel pump, flexing constantly to keep fuel moving. Over time, they get stiff or worn, especially with today’s fuel. It’s a small part, but when you replace it, you can feel the motor come back to life.\u003c\/p\u003e\n\u003chr data-start=\"443\" data-end=\"446\"\u003e\n\u003ch2 data-section-id=\"1ma7m6t\" data-start=\"448\" data-end=\"463\"\u003eKey Features\u003c\/h2\u003e\n\u003cul data-start=\"464\" data-end=\"928\"\u003e\n\u003cli data-section-id=\"115kvey\" data-start=\"464\" data-end=\"558\"\u003ePulse-Driven Fuel Operation – Uses engine pressure pulses to move fuel through the system.\u003c\/li\u003e\n\u003cli data-section-id=\"t40csa\" data-start=\"559\" data-end=\"650\"\u003eFlexible Performance Material – Designed to flex consistently for steady fuel delivery.\u003c\/li\u003e\n\u003cli data-section-id=\"5hbgtm\" data-start=\"651\" data-end=\"741\"\u003eOEM Fit and Seal – Built to Yamaha specifications for proper installation and sealing.\u003c\/li\u003e\n\u003cli data-section-id=\"9kxo6k\" data-start=\"742\" data-end=\"837\"\u003eRestores Fuel Pump Efficiency – Helps eliminate fuel starvation and uneven engine behavior.\u003c\/li\u003e\n\u003cli data-section-id=\"1a2qtoi\" data-start=\"838\" data-end=\"928\"\u003eIdeal Maintenance Component – Common replacement during fuel pump service or rebuilds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr data-start=\"930\" data-end=\"933\"\u003e\n\u003ch2 data-section-id=\"1qx5o2j\" data-start=\"935\" data-end=\"965\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/h2\u003e\n\u003cp data-start=\"966\" data-end=\"1219\"\u003eDesigned for Yamaha outboards equipped with compatible fuel pump systems.
