Description

Yamaha - Fuel Pump Diaphragm - Fuel Delivery Component - 6H4-24411-00-00

Overview

When a motor starts acting like it’s not getting enough fuel, this is one of the first things I check. 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.

Key Features

  • Pulse-Driven Fuel Operation – Uses engine pressure pulses to move fuel through the system.
  • Flexible Performance Material – Designed to flex consistently for steady fuel delivery.
  • OEM Fit and Seal – Built to Yamaha specifications for proper installation and sealing.
  • Restores Fuel Pump Efficiency – Helps eliminate fuel starvation and uneven engine behavior.
  • Ideal Maintenance Component – Common replacement during fuel pump service or rebuilds.

Engine & Boat Compatibility

Designed for Yamaha outboards equipped with compatible fuel pump systems. Commonly used across small to mid-size engines found on fishing boats, skiffs, and recreational vessels. Always verify compatibility with your specific engine before installation.

FAQ

Q: What are signs this diaphragm is failing?
A: Hard starting, stalling, or loss of power—especially at higher speeds—are common signs.

Q: Can ethanol fuel damage this part?
A: Yes, ethanol can cause the material to stiffen or break down over time.

Q: Should I replace the whole fuel pump or just the diaphragm?
A: If other parts show wear, a full rebuild kit is usually the better option.

Q: Is installation difficult?
A: Not typically, but it’s important to keep everything clean and aligned during assembly.

Q: How often should this be replaced?
A: It depends on usage, but it’s good practice to inspect it during routine fuel system maintenance.
