Yamaha - Primer Pump Assembly - Fuel System Component - 6BX-24360-10-00

Overview

If your motor’s hard to start or takes a few extra squeezes to get going, this is usually where the problem starts. The primer pump is what gets fuel moving before the engine fires, and when it’s weak or leaking, everything feels off right from startup. I’ve replaced plenty of these on older setups, and it’s one of the quickest ways to bring back easy, reliable starts. It’s simple, but you notice it every time you turn the key.

Key Features

• Manual Fuel Priming – Allows quick fuel delivery to the engine before startup.

• Improved Cold Starts – Helps eliminate extended cranking and hard starting issues.

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

• Durable Fuel Resistant Build – Designed to withstand fuel exposure and repeated use.
