Yamaha - Pump Damper - Fuel System Component - 6C5-13781-00-00

Overview

This is one of those small parts that keeps the fuel system running smoother than you’d expect. The pump damper helps absorb pulses and vibration so fuel delivery stays steady instead of jumping around. When it starts to wear out, you might notice the engine feeling a little rough or inconsistent, especially at idle or mid-range. Swapping it out helps bring things back to a smooth, predictable run.

Key Features

• Vibration Dampening Design – Reduces fuel system vibration for smoother operation.

• Stabilized Fuel Flow – Helps maintain consistent pressure and delivery to the engine.

• OEM Fit Accuracy – Matches Yamaha factory specs for proper installation and function.

• Fuel Resistant Construction – Built to handle constant fuel exposure and engine heat.
